Answer and explanation

Correct answer

A. Copy or rebuild data intentionally when you need a new version instead of quietly mutating shared state. Candidates who speak clearly about mutation sound safer to trust with data-heavy systems.

Why

Interviewers usually care less about keywords than about whether you can explain why the code is shaped the way it is.
