The correct answer is

THJ

Track the first letters: D(4), U(21), L(12), C(3); the jumps are +17, −9, −9, so the next jump is +17 giving C(3) + 17 = T.

Track the second letters: R(18), I(9), Z(26), Q(17); the jumps are −9, +17, −9, so the next jump is −9 giving Q(17) − 9 = H.

Track the third letters: T(20), K(11), B(2), S(19); the jumps are −9, −9, +17, so the next jump is −9 giving S(19) − 9 = J.

Combining the three letters gives T, H, J.

Hence, the missing cluster is THJ.
