C.If the numerator and denominator have no common factor other than 1.
Answer:
C
Explanation:
Because letter A means it will be 1/1 which is a no no..
letter B means that they are factored completely but not with their common factors..
letter C means that they were factored completely by their common factors.. which is right
and letter D means that they'll not have a common factor but -1.. and that's also wrong
So therefore, the answer will be letter C
