B Correct answer
Explanation

The PERFORM VARYING loop executes with C starting at 1 and incrementing by 1 until C reaches 6. This means the loop runs when C = 1, 2, 3, 4, 5 (5 iterations total). Each iteration increments RESULT by 1, starting from 0, so the final value is 5. The loop stops before executing when C = 6.
