C

Step-by-step explanation:

1. Elimination

First we have to eliminate everything that is equal or below 20.

A. 12 + 21 = 33 > 20- Good

B. 16 + 9 = 25 > 20 - Good

C. 10 + 15 = 25> 20 - Good

D. 8 + 12 = 20 = 20 - Bad

So our other options are A, B, and C

2. Find the answers

So now we have to solve each one

A. 12 white marbles and 21 blue marbles = 12/21

12/21 = 2/3 - False

B. 16 white marbles and 9 blue marbles = 16/9

16/9 = 2/3 = False

C. 10 white marbles and 15 blue marbles

10/15 = 2/3 - True

C is the answer
