Four letter-clusters have been given, out of which three are alike in some manner and one is different. Select the odd
letter-cluster.
J +Â 4 = N + 3 = Q + 2 = S
T +Â 2 = V +Â 2 = X +Â 2 = Z
R +Â 1 = S +Â 1 = T + 1 = U
A + 3 = D + 3 = G + 3 = J
Except option A, remaining all letter-clusters have same difference in between the letters.
$$\therefore$$ The correct answer is option A.
