The correct answer is Option 3: Both 1 and 2.

Explanation:

Aadhaar is India`s national identity system, which assigns a unique 12-digit identification number to residents based on their biometric and demographic data. It provides an open Application Programming Interface (APIs) that allows developers to integrate Aadhaar authentication services into their applications and electronic devices.

1. It can be integrated into any electronic device:

The statement is correct. The open APIs provided by Aadhaar allow developers to integrate Aadhaar authentication services into any electronic device, such as smartphones, laptops, tablets, and other internet-connected devices. This means that electronic devices can use Aadhaar authentication to verify the identity of users for accessing various services or transactions, such as banking, e-commerce, government services, etc.

2. Online authentication using iris is possible:

The statement is also correct. Aadhaar authentication services support multiple biometric authentication factors, including iris recognition, fingerprint recognition, and facial recognition. This allows users to authenticate their identity online using their biometric data, without the need for physical documents or tokens. The iris recognition technology used in Aadhaar is one of the most secure and accurate biometric authentication methods, making Aadhaar authentication highly reliable and secure.

In conclusion, both statements are correct. The open APIs provided by Aadhaar allow for easy integration with any electronic device, and the biometric authentication factors, including iris recognition, make online authentication highly secure.
