उत्तर और व्याख्या · explanation in English
Answer: (b) TSPO
Letters shift alternately forward and back by one: Z → A (+1), E → D (−1), R → S (+1), O → N (−1). Applying +1, −1, +1, −1 to S, T, O, P gives T, S, P, O.
- Z + 1 = A, E − 1 = D, R + 1 = S, O − 1 = N.
- S + 1 = T, T − 1 = S, O + 1 = P, P − 1 = O.
- STOP → TSPO.
Remember · Coding items: write the shift for each letter position; alternating patterns are common.
