Solution:The pattern followed here is :(1st letter - 2 = 2nd letter), (2nd letter - 4 = 3rd letter) & (3rd letter - 6 = 4th letter)
TRNH → (T - 2 = R), (R - 4 = N) & (N - 6 = H)
OMIC → (O - 2 = M), (M - 4 = I) & (I - 6 = C)
RPLF → (R - 2 = P), (P - 4 = L) & (L - 6 = F)
But,
WTPK → (W - 2 ≠ T), (T - 4 = P) & (P - 6 ≠ K)
Hence, WTPK is the correct answer.
