Find the missing character?

Answer: Option C

Writing each letter as its numerical value and working in rows, add the top 2 digit number to the bottom 2 digit number to give the 3 digit result in the center.
I and F = 9 and 6 = 96
And,
E and G = 5 and 7 = 57
Now,
96 + 57 = 153 = AEC.
Missing Character = A.
