To solve this question, the user needs to know the concept of encoding and decoding using a specific pattern or rule.
Each letter in the word 'CODING' has been shifted one letter forward in the English alphabet. For example, 'C' becomes 'D', 'O' becomes 'P', and so on.
Using the same pattern, we can decode the word 'CURFEW' as follows:
'C' becomes 'D'
'U' becomes 'V'
'R' becomes 'S'
'F' becomes 'G'
'E' becomes 'F'
'W' becomes 'X'
Therefore, the encoded form of the word 'CURFEW' is 'DVSGFX'.
