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

Concept: In a letter analogy of the form A : B :: C : ?, the same alphabet-shift rule that transforms the first pair into the second pair must be applied uniformly to every letter of the third group to get the answer.

1. Compare AEIM with BFJN letter by letter: A→B, E→F, I→J, M→N — each letter moves forward by exactly one position in the alphabet.

2. So the governing rule is a uniform +1 shift applied to every letter of the group.

3. Apply the same +1 shift to CGKO: C→D, G→H, K→L, O→P.

Cross-check: each of the four shifts (C→D, G→H, K→L, O→P) is exactly one alphabet position forward, matching the shift size confirmed in the first pair, so the transformation is consistent across all four letters.

This gives the sequence DHLP.
