D) The coins may not be the same size

Explanation:

If we look at the drawings, we can tell that all 4 coins appear to be circular, eliminating answer choice A. Since the question asks us to compare the size of the stones, answer choice B is irrelevant since it asks about color.

While it is true the coins have a different value, the better answer, in this case, is because the coins are different sizes, because this doesn't provide a basis to compare the size of each stone.

For example, let's say I compared a small rock to a very small coin, and then the same exact small rock to a large coin. In this example I provide, while both rocks are the same size, placing the small rock next to a large coin makes it hard to have an objective basis for comparing the two.
