In a certain code, BOOK is written as DQQM. Using the same rule, how will FILE be written?
FILE is coded as HKNG. The example shows every letter shifted two places forward in the alphabet: B becomes D, O becomes Q and K becomes M. Applying the same shift, F becomes H, I becomes K, L becomes N and E becomes G.

Explanation
In BOOK to DQQM each letter moves forward by 2 places (B→D, O→Q, K→M). Applying this to FILE gives F→H, I→K, L→N, E→G, so HKNG. Option GJMF shifts each letter by only 1 place, which does not match the given example.
