Select the next element of the series : Z, WV, RQP, _______

The correct option is KJIH.

To find the next element of the series, we can analyze the pattern of the letters by writing the English alphabet in reverse order:
Z, Y, X, W, V, U, T, S, R, Q, P, O, N, M, L, K, J, I, H, G, F, E, D, C, B, A

Let us examine the transition between the terms step-by-step:

1. First term: "Z"
This term contains 1 letter: Z.
We skip the next 2 letters in the reverse sequence: Y and X.

2. Second term: "WV"
This term contains 2 consecutive letters in reverse order: W and V.
We skip the next 3 letters in the reverse sequence: U, T, and S.

3. Third term: "RQP"
This term contains 3 consecutive letters in reverse order: R, Q, and P.
Following the pattern of increasing the number of skipped letters by 1 each time, we must now skip the next 4 letters in the reverse sequence: O, N, M, and L.

4. Fourth term (Next element):
Following the pattern, this term must consist of 4 consecutive letters in reverse order starting immediately after the skipped letters (L).
These letters are K, J, I, and H, which gives KJIH.

Therefore, the next element of the series is KJIH.
