Correct answer: A

Concept: In a letter-shift (substitution) code, each letter of the original word is replaced by the letter a fixed number of places away from it in the alphabet. The same shift is applied to every letter, and the letters keep the order in which they appear in the original word. The alphabet is treated as a cycle, so a backward shift that runs past A continues from Z.

Application: compare the given word with its code, letter by letter, to find the shift.

  1. M (13th letter) becomes K (11th letter): 2 places back.

  2. O (15th letter) becomes M (13th letter): 2 places back.

  3. H (8th letter) becomes F (6th letter): 2 places back.

  4. A (1st letter) becomes Y (25th letter): 2 places back, wrapping through Z.

  5. N (14th letter) becomes L (12th letter): 2 places back.

The shift is the same at every position, so the rule is: move each letter 2 places back in the alphabet. Applying that rule to COUNT:

Reading the code letters in the same order gives AMSLR.

Cross-check: moving each letter of AMSLR 2 places forward gives C, O, U, N and T, which rebuilds the original word, so the coding works in both directions. Because the shift is applied position by position, the code letters must appear in the same sequence as the letters of the original word.
