  1. 16.5 m.

  2. 56.4 m.

  3. 12.33 m.

  4. 44 m.

A Correct answer
Explanation

The height difference between poles is 80 - 63.5 = 16.5 m. Since the line joining tops makes a 45° angle with horizontal, the horizontal distance equals the vertical difference. Using tan45° = 1 = opposite/adjacent, the distance = 16.5 m. This matches the claimed answer A.
