Which of the following terms will replace the question mark (?) in the given series to make it logically complete?
E12JZ, M16RH, U20ZP, C24HX, ?

Given: E12JZ, M16RH, U20ZP, C24HX, ?

Logic: The first letters progress by 8 positions forward in the alphabet, numbers increase by 4, and the last two letters move 8 positions forward in the alphabet.

First letters (E, M, U, C): 

E + 8 → M 

M + 8 → U

U + 8 → C

C + 8  → K 

Numbers (12, 16, 20, 24):

The numbers increase by 4 each time:

12 + 4 = 16

16 + 4 = 20

20 + 4 = 24

24 + 4 = 28

Last two letters (JZ, RH, ZP, HX):

JZ → RH (moves 8 places forward in the alphabet for both letters)

RH → ZP (moves 8 places forward for both letters)

ZP → HX (moves 8 places forward for both letters)

HX → PF (moves 8 places forward for both letters)

Thus, the next term is K28PF.

Correct answer is (d)
