Select the related word/letters/number from the given alternatives. PEON :…

Concept: This type of letter analogy is built on a two-step code -- a positional shift, where a fixed number is added to (or subtracted from) each letter's place in the alphabet, followed by a structural rearrangement of the shifted letters, such as reversing their order. The rule (shift amount and rearrangement) is first worked out from the given pair, then applied identically to the second word.

Application:

1. Find the alphabet position of each letter of PEON: P=16, E=5, O=15, N=14.

2. Add 3 to each position: P->S(19), E->H(8), O->R(18), N->Q(17), giving the shifted word SHRQ.

3. Reverse SHRQ letter by letter: S-H-R-Q reversed is Q-R-H-S, i.e. QRHS -- exactly the given output, confirming the rule is +3 shift then reverse.

4. Apply the same rule to JOCK: positions are J=10, O=15, C=3, K=11.

5. Add 3 to each: J->M(13), O->R(18), C->F(6), K->N(14), giving the shifted word MRFN.

6. Reverse MRFN letter by letter: M-R-F-N reversed is N-F-R-M, i.e. NFRM.

Cross-check: Reversing NFRM back gives MRFN, and subtracting 3 from each of its letters (M->J, R->O, F->C, N->K) restores JOCK exactly, confirming the derivation is consistent in both directions.
