Correct option is C
Given:

Logic: Each letter in the diagram is paired with its opposite letter in the English alphabet.

Q (17) ↔ J (10)
C (3) ↔ X (24)
G (7) ↔ T (20)
H (8) ↔ S (19)
The missing letter should be opposite of G (7) → T (20)
Thus, the correct option is (c) T
C (3) ↔ X (24)
G (7) ↔ T (20)
H (8) ↔ S (19)
The missing letter should be opposite of G (7) → T (20)
Thus, the correct option is (c) T
