The answer looks like C.

Step-by-step explanation:

Combine any like terms on each side of the equation: x-terms with x-terms and constants with constants. Arrange the terms in the same order, usually x-term before constants. If all of the terms in the two expressions are identical, then the two expressions are equivalent. That is how you find which expression is equivalent.

C. p^16/q^12

Step-by-step explanation:

The reason why the answer would be p^16/q^12 would be because, that if it is exponents. You always. Always. Subtract or Add depending if its multiplication or subtraction. So p^24-p^8 would be p^16. q^4-q^12 would be q^12.

Therefore, your answer would be p^16/q^12
