A Correct answer
Explanation

The PERFORM statement executes b-para exactly 5 times because ws-n is 5 when the PERFORM begins. The fact that b-para changes ws-n to 10 does not affect the already-determined iteration count. PERFORM evaluates the loop count once at the start, not after each iteration. This is a fixed iteration loop, not a conditional one.
