The correct answer is C.

In this problem, we can write a system of three equations and three variables.
Let’s review the equations.
A + B + C = 9 or 19
A + A + C = 5 or 15
A + A + A = 13 or 12
3A cannot be 13. Therefore, 3A = 12 ⇒ A = 4
We can also conclude that in the second equation:
A + A + C = 15 ⇒ 2A + C = 15 ⇒ C = 7
Or A + A + C = 16 (1 may added from the first column)
C = 6
Try different values for the first equation:
A + B + C = 9 or 19
If A = 4 and C = 6 ⇒ B = 9
If A = 4 and C = 7 ⇒ B = 8
B + C = 15
