C Correct answer
Explanation

The PERFORM loop displays WS-COUNT BEFORE incrementing it. Initial value is 1, condition is WS-COUNT >= 2 (false for 1), so it enters loop, displays 1, then adds 1 (becomes 2). Next iteration checks condition: 2 >= 2 is true, so loop exits. Only 1 is displayed. The loop structure ensures display happens first, then increment.
