It is given that hill tops of A&B are intervened y third top, but height of third top is not given.
Therefore, m not able to understand how option B is correct.
Question is not clear to me.

The answer should be C. In the question it is clearly. Defined that all the three hills top are occupied by contour of same value. Hence top point A, B and C are in the same line of sight.

How answer would be 'B'?
I think answer 'C' would be right.

Line of sight will diverges downwards with distance. So B is the answer.

Hi, @Snehangsu.
B is the correct answer because if the line of sight from A to B and C is the intervened point then obviously the line of sight passes below the hill top at C its because of the curvature of the earth.

Is Earth Curvature considered when distance taking more than 250km?
