Loop unrolling is a code optimization technique:

  1. That avoids tests at every iteration of the loop.
  2. That improves performance by decreasing the number of instructions in a basic block.
  3. That exchanges inner loops with outer loops
  4. That reorders operations to allow multiple computations to happen in parallel




Answer : A,

Explanation:
