Explanation

Losing a USB stick means an unknown party now has physical access to its contents, which directly violates confidentiality - the principle that information is only accessible to those authorized to see it. Option A (integrity) is wrong because integrity refers to data being accurate and unaltered; losing the stick doesn't change or corrupt the data itself. Option B (availability) is wrong because availability means authorized users can access data when needed - while you lose access, the concern here is that unauthorized people gain it, which is a confidentiality issue, not availability. The key distinction to remember for exams is the CIA triad: Confidentiality = who sees it, Integrity = is it accurate, Availability = can you get to it - and losing a device to a stranger is always a confidentiality breach.
