If in a certain code language ‘GAP’ is written as ‘FHZBOQ’, ‘NET’ is written as ‘MODFSU’, then how will ‘TONE’ be written in that language?

The given examples show that each letter in the word is replaced by the previous letter and the next letter in the English alphabet.

For example, in 'GAP':

• 'A' is replaced by 'Z' (the previous letter) and 'B' (the next letter)
