I am pretty sure the answer to this question is letter A. I remember learning this but i dont remember it clearly.
The perfect squares are 25, 36, 49, 64, 81, 100, 121, 144, 169. You know a number is a perfect square when there is a whole number that can be multiplied by itself to get the number. Example: 25= 5x5
