Concept:The analogy uses a pattern of adding or subtracting specific numbers to each letter's position in the alphabet.Explanation:Assign numbers to letters: A=1, B=2, ..., Z=26.In ACE: A(1) becomes B(2) → +1; C(3) becomes B(2) → -1; E(5) becomes G(7) → +2.So the shifts are +1, -1, +2.Apply same shifts to XYP: X(24)+1 = 25 → Y; Y(25)-1 = 24 → X; P(16)+2 = 18 → R.Thus the result is YXR.
