B. Every point on each has the same elevation.
C. The shore of the lake will exactly follow a contour line.
D. All of the above are true.

Answer 1

The answer should be D, All of the above are true. 

Answer 2

Answer:

option D, All of the above are true.

Explanation:

A contour is a surveying terminology that is used to represents dots of similar elevation joined together by line.  All the points lying on any contour line are horizontal and have same elevation. Mostly contours are used to represent any elevation such as mountain, hill etc or a depression such as lake, river etc.

The same is the scenario with a calm lake, where all the surface points are horizontal and at same height. Therefore the shore of the lake will exactly follow a contour line. Hence, Option D is correct.
