Exam CIPT topic 1 question 154 discussion

The correct answer is A. Identification. The privacy technologist is concerned about the threat of identification, as collecting a full date of birth could make it easier to identify an individual, increasing the risk of privacy breaches. By asking if an individual is over 18 instead, the organization can reduce the amount of personal data collected, minimizing this risk.

It could be D and A BUT D is make more sense for me... Why D for me is correct? Data minimization involves collecting only the data that is necessary for the specific purpose and avoiding the collection of additional personal information. By asking only whether the individual is over 18, the organization limits the amount of personal information collected and reduces privacy risks. also in the question "As the service is not aimed at children" gives an indication that the question is not aiming for some Identification thing :) !

Is minimization a threat？？
