Which of the following terms will replace the question mark (?) in the given series?
CJS, DKT, ELU,?

The correct answer is FMV.

To find the next term in the series, let us analyze the pattern followed by each letter position in the consecutive terms:
The given series is: CJS, DKT, ELU, ?

1. First Letter Pattern:
C → D → E → ?
The first letters are consecutive English alphabets:
C (+1) = D
D (+1) = E
E (+1) = F

2. Second Letter Pattern:
J → K → L → ?
The second letters are also consecutive English alphabets:
J (+1) = K
K (+1) = L
L (+1) = M

3. Third Letter Pattern:
S → T → U → ?
The third letters are also consecutive English alphabets:
S (+1) = T
T (+1) = U
U (+1) = V

Combining the next letters from each step, we obtain the term FMV.
