A series is given with one term missing. Select the correct alternative from the given ones that will complete the series.
NRTS, JNPO, FJLK, BFHG, ?

Correct option is C

Logic: Each letter is decreasing by 4 places in the next
N – 4 = J, J – 4 = F, F – 4 = B, B – 4 = X
R – 4 = N, N – 4 = J, J – 4 = F, F – 4 = B
T – 4 = P, P – 4 = L, L – 4 = H, H – 4 = D
S – 4 = O, O – 4 = K, K – 4 = G, G – 4 = C
XBDC, is correct answer.
Thus, correct option is (c).
