Which of the following options should come in place of the questions mark (?) in the given series based on the English alphabetical Order?

BEV , FIR , JMN , NQJ , RUF , ?

Given: BEV , FIR , JMN , NQJ , RUF , ?

Logic: In this given alphabet series 1s letter is increasing by +4, 2nd is by +4 and 3rd is decreasing by -4

B + 4 = F, F +4 = J, J +4 = N, N+4 = R , R +4 = V

E + 4 = I, I +4 = M, M+4 = Q, Q+4 = U, U +4 = Y

V - 4 = R, R - 4 = N, N - 4 = J, J - 4 =F, F - 4 = B
