Show answer & explanation
Correct answer: A
Peep-hole optimization is a standard compiler technique that operates on small, contiguous windows of code instructions to improve efficiency. It works by examining a local window of the intermediate code, applying optimizations, and repeating this process until no further improvements can be made (convergence).
