Step 1: Understanding the Concept:
An Aadhaar card is a 12-digit unique identity number issued by the Unique Identification Authority of India (UIDAI) on behalf of the Government of India. It serves as a proof of identity and address.
Step 2: Detailed Explanation:
A standard Aadhaar card contains the following demographic and biometric information of the holder:
Name
Photograph
Address
Date of Birth (from which Age is determined)
Gender
12-digit Aadhaar number
Biometric information (fingerprints and iris scan), which is stored in the database but not printed on the card.
Since the card explicitly mentions the holder's Name, Address, and Date of Birth (Age), all the given options are correct.
Step 3: Final Answer:
An Aadhaar card contains the holder's name, address, and age (via date of birth). Thus, the correct option is 'All of these'.
