Correct Answer - Option 1 : Hill : Moutain
The logic followed here is:
Pond and Lake both are waterbodies but a pond is usually less deep and smaller in area than a lake.
Similarly, hill and mountain, both are landforms that are elevated portion of Earth's crust but a hill is usually less steep and not as tall as a mountain.
Thus, Hill : Mountain is related to Pond : Lake by the same logic.
Hence, Hill : Mountain is the correct answer.
