Which letter cluster will replace the question mark (?) to complete the given series?
YFJW, BJEC, ?, HRUO, KVPU

YFJW, BJEC, ?, HRUO, KVPU

Logic: Alternate letters are shifted +3, +4, -5, +6 positions in the alphabet.​

First Letters: Y + 3 → B, B + 3 → E, E + 3 → H, H + 3 → K

Second Letters: F + 4 → J, J + 4 → N, N + 4 → R, R + 4 → V

Third Letters: J - 5 → E, E - 5 → Z, Z - 5 → U, U - 5 → P

Fourth Letters: W + 6 → C, C + 6 → I, I + 6 → O, O + 6 → U

So, the next term will be: ENZI

Thus, the correct option is: (d)
