O, N, L, K, I, H, F, ?
Option 1: A

Option 4: H
Correct Answer: E
Solution :
Given:
O, N, L, K, I, H, F, ?
In the above-given series, subtract 1 and 2 alternately from the place values of the letters.
O – 1 = N; N – 2 = L; L – 1 = K; K – 2 = I; I – 1 = H; H – 2 = F; F – 1 = E
So, E is the missing letter of the series. Hence, the second option is correct.
