The terms `Pinaka and Smerch` mentioned in the news recently refer to rocket launcher systems. Rocket launcher systems are designed to launch rockets over long distances with precision. They are often used in military operations to target enemy positions or infrastructure.
Cruise missiles, option 1, are self-propelled guided missiles that are designed to fly at low altitudes over long distances. They are different from rocket launcher systems as they are not launched from the ground, but rather from ships, submarines, or aircraft.
Nuclear-powered submarines, option 2, are submarines that are powered by a nuclear reactor. They are used for various purposes, including surveillance, intelligence gathering, and as a deterrent force. However, the terms Pinaka and Smerch do not refer to nuclear-powered submarines.
Weaponized drones, option 4, are unmanned aerial vehicles (UAVs) that are equipped with weapons such as missiles or guns. They are used for military purposes, including reconnaissance, surveillance, and targeted strikes. However, the terms Pinaka and Smerch do not refer to weaponized drones.
In conclusion, the correct answer is option 3 - rocket launcher systems.
