Collecting only what a task actually needs reflects:
A. Data minimisation and purpose limitation✓ 答案
B. Keeping every contact detail permanently in case it is useful
C. Publishing account details to show transparency
D. Collecting everything first and filtering later
解說
Collecting the minimum limits the harm if the data is lost or misused and keeps the task proportionate. Holding more than necessary increases breach exposure and weakens the justification for any later reuse.
