0. Loop unrolling is a code optimization technique:
- Option : A
- Explanation : Loop unrolling is a code optimization technique that avoids tests at every iteration of the loop. It does not improves performance by decreasing the number of instructions in a basic block. Neither it exchanges inner loops with outer loops nor it reorders operations to allow multiple computations to happen in parallel. So, option (A) is correct.
