Which English meaning corresponds to passer inaperçu?

• A. To go undetected
• B. To go unnoticed
• C. To be seen
• D. To vanish

Answer: (A)

The main idea here is evading being noticed. Passer inaperçu describes slipping by without drawing attention or being detected by others. In English, the natural match is “to go undetected”—it emphasizes that there was a chance to be detected, but you weren’t. While “to go unnoticed” is very close, “undetected” carries the sense of not being detected by observers or detectors, which aligns more directly with the nuance of the original phrase. The other options don’t fit because they either express the opposite (“to be seen”) or a complete disappearance not implied by simply avoiding detection (“to vanish”). For example, a person who moves past security without triggering a notice has gone undetected.
