B Correct answer
Explanation

Statement I (perimeter = 44 m) and Statement II (height = 10 m) together are sufficient. The total wall area = perimeter × height = 44 × 10 = 440 sq m. Cost = 440 × 25 = Rs 11,000. Statement III alone is insufficient, and I + III can solve but are not required when both I and II are available.
