Answer: (d)D.

PHONE

Why this answer is correct

The pattern for the code is as follows,

Each letter at odd place in the word is one step behind and each letter at even place in the word is one step ahead of the corresponding letter of the code.

So, to get the word from the code apply this pattern in reverse order (instead of + take – and vice versa)

Therefore, PHONE is written as QGPMF.
