In which of the following areas can GPS technology be used ? 1. Mobile phone operations 2. Banking operations 3. Controlling the power grids Select the correct answer using the code given below :

Mentions GPS as a tool to discover shortest routes for transporting goods and lists payments via mobile/UPI as an example of technology in payments.

A student could combine GPS route-finding with mobile payment systems to infer GPS could help logistics (cash-in-transit routing) or merchant/payment location verification.

States GPS is a handy tool to find exact locations and that technology (GIS/GPS) enhances data handling and analysis.

Using basic knowledge that banks maintain assets/branches and deliver services, one can extend this to possible uses like branch/ATM mapping, asset tracking, or location-based customer services.

Describes e-rupee functioning with digital wallets on mobile devices and transactions recorded in banks' Core Banking Solution (CBS).

A student could reason that mobile wallets on devices can expose location metadata (via GPS) to support fraud detection, merchant proximity checks, or location-tagged transactions.

Explains payment banks will capitalise on mobile technology and applications to deliver services and be cost-efficient.

Combine this with GPS being available on mobiles to infer potential banking uses such as agent location services, customer onboarding (KYC verification), or proximity-based offers.

Defines Core Banking Solution (CBS) as online, networked banking enabling customers to operate accounts from anywhere on the bank's network.

Given CBS centralises transactions, a student could posit GPS-derived location data from client devices might be integrated with CBS for context-aware services or security checks.

This snippet links two systems — satellites/GPS and power grids — by noting geomagnetic storms can disrupt GPS and simultaneously cause large disturbances in electric power grids.

A student could combine this with the basic fact that GPS satellites provide positioning/timing services to ask whether grids rely on that timing/positioning and thus would be affected if GPS were used for control/synchronization.

Describes practical uses of GPS for tracking and automated navigation of robots/drones, showing GPS is already used to control and coordinate remote equipment.

Extend by reasoning that if GPS can enable remote control and automated coordination of vehicles, similar positioning or synchronization could assist distributed grid assets (e.g., drones inspecting lines, or coordinating mobile resources).

Defines GPS as a technology that discovers routes and supports automated functions, illustrating GPS is a general-purpose enabling technology for control and coordination.

A student could infer that such enabling roles (navigation, synchronization) might be transferable to managing/monitoring grid components across large areas, then check technical literature on grid control needs.

Emphasizes that electrical systems require precise control 'to a fraction of a second', highlighting the importance of accurate timing in power-system operations.

Combine this with the common fact that GPS provides precise time signals to hypothesize GPS could be used for grid synchronization and time-stamping of events, then verify in technical sources.

Discusses large-scale/transnational electricity grids (OSOWOG) where coordination across long distances is central, implying a need for reliable communication, monitoring, and coordination tools.

A student might reason that cross-region grid control needs accurate coordination and ask whether GPS-based timing/positioning is one practical tool to achieve that at scale.
