Explanation
- A
1 only
(a) 1 only. Open APIs do allow Aadhaar authentication to be built into devices and applications, but statement 2 is also true: iris is an Aadhaar biometric and can be used online where devices support it. Stopping at 1 only is incomplete.
- B
2 only
(b) 2 only. Iris authentication is possible, yet the API implication is broader than iris alone. Isolating statement 2 misses statement 1, so this is not the key.
- C
Both 1 and 2
(c) Both 1 and 2. (c) Official key: UIDAI published open APIs so Aadhaar can be integrated into electronic devices and services, including biometric modes such as iris. Both statements follow from that platform design.
- D
Neither 1 nor 2
(d) Neither 1 nor 2. Both implications are real, so ‘neither’ is not the key.
Summary. Official key is (c) both 1 and 2. Aadhaar’s open APIs let developers embed authentication in devices and apps. Online iris authentication is a supported biometric mode alongside fingerprint and OTP. Honour the stored letter (c).
