Hello there, and thank you for posting your question here on brainly.
Short answer: C. Product of 2 rational numbers = a rational number.
Why?
The numbers are both rational because squared is a result of a number multiplied by itself. Like (3^2 = 9). It turns out as a rational number because you're multiplying by two positive numbers, which always turns out as a rational number. (3^2 * 4^2 ==> 144) [3^2 = 9] [4^2 = 16]
Hope this helped you! ♥
