The term "squares" means that both of the terms in the expression are created by squaring rational numbers and/or variables.
"x" squared is x², and that is the first term in every choice. So we need to check each of the constants (numbers without variables).
1²=1 (from option A), 2²=4 (from option B), and 4²=16 (from option D), so that leaves option C. The number 8 is not a perfect square number, so x²-8 is not a difference of squares.
