Answer:
C
Explanation:
If you were to simplify each one given. Three of those options turn into decimals, which is not acceptable.
To simplify each fraction you would get the numerator 13 and divide them by the numerators given in the multiple choice. Same with the denominator, take the 39 and divide them by the other denominators given in the multiple choice.
The only one that didn't give a decimal is C. 1/3
because
13÷1=13
39÷3=13
