Correct option is D
Given:


Logic: Sum of position of left and right square letters = Circle letter position in middle.
In 1st row:
P (16) + D (4) = T (20)
In 2nd row:
J (10) + G (7) = Q (17)
Similarly, in row 3rd:
C (3) + O (15) = ?
? = R (18)
So, the missing number is R
Thus, the correct option is (d)
