In a certain code language, each letter is replaced by the letter that comes immediately before it in the English alphabet. How will the word MARKET be written in this code?
MARKET is coded as LZQJDS. Each letter is moved one place back in the alphabet, so M becomes L, A wraps around to Z, R becomes Q, K becomes J, E becomes D and T becomes S.

- BNBSLFU
- CLZQJDU
- DLAQJDS
Explanation
Shift each letter back by one: M→L, A→Z, R→Q, K→J, E→D, T→S. This gives LZQJDS. LZQJDU is wrong because the last letter T was wrongly shifted to U or mishandled; NBSLFU shifts forward instead of backward.
