Why couldn't column A be 4?

Sarah, column A can be 4, which is the square root of 16, and the square of 2, which is an integer.
But x can also be 1, which is the square root of 1, and the square of 1, which is also an integer.
But x can also be 1, which is the square root of 1, and the square of 1, which is also an integer.

Since it can be 4 why isn't the answer D?

Dusty, because x can also be 1, or 4. So there's not enough information to decide.

I came up with D as the correct answer for the exact reason given in the comment. But when I hit "show solution" the solution was A. Can you please fix that? Thanks

Correction, the solution says:column b is larger

Mona and Dusty, I agree with you that the question can be misleading. It would have been clearer if it had said "x is the square root and the square of the same integer". Even I got the answer incorrect based on the explanation. We will correct the wording of the sentence.

The answer still says B
