The correct answer is

UQV 54

Track each letter position and the number separately.

First letters: G, D, A, X each decrease by 3 (wrapping), so the next is \(X-3=U\).

Second letters: C, Z, W, T each decrease by 3, so the next is \(T-3=Q\).

Third letters: H, E, B, Y each decrease by 3, so the next is \(Y-3=V\).

Numbers: 10, 21, 32, 43 increase by 11 each time, so the next is \(43+11=54\).

Combining gives UQV 54.

Hence, the required cluster is UQV 54.
