If we add two 2-digit numbers and the sum is a 3-digit number, then the 3-digit number must start with a 1.
So, E = 1

In order for the sum to be a 3-digit number, A+C must be greater than 9
So, we have two options:
EITHER A and C are 5 and 6, OR A and C are 4 and 6
If A and C are 5 and 6, then F = 1, but we already know that E = 1
So, it MUST be the case that A and C are 4 and 6, which means F = 0

The three digits unaccounted for are 2, 3 and 5
Since we can see that B + D = G, it must be the case that G = 5

Answer: D

Cheers,
