• A facial image of a child is taken instead of fingerprint for enrolment. 
• It is a blue-coloured variant of the Aadhaar Card which is issued for children below the age of 5 years. 

CAG criticism of Bal Aadhar 

• The audit was also critical of UIDAI’s move to issue Aadhaar cards to children and newborns without biometrics under an initiative known as Bal Aadhaar. 
• This needs to be reviewed because anyway after 5 years, a child has to apply for a new regular Aadhar.

Hence option 3rd is correct.
