Question: Which of the following is not a required component of Aadhaar card issued by UIDAI?

Answer:

Voice recording is not a mandatory component of an Aadhaar card issued by UIDAI (Unique Identification Authority of India). The primary components of an Aadhaar card typically include a unique Aadhaar number, demographic information, and biometric data such as fingerprints and iris scans. However, please note that there may have been updates or changes since then, so it's advisable to refer to the official UIDAI website for the latest information on Aadhaar card requirements.
