The correct option is A WUSQO
Given, BDFHJ is written as IGECA.
Here the letter of the word 'BDFHJ' are written in a reverse order and then each letter is moved one step backward to obtain the code 'IGECA' as:
The reverse order of the word 'BDFHJ' is 'JHFDB'.
Now, each letter is moved one step backward to get the code 'IGECA'.
Similarly, the reverse order of the word 'PRTVX' is 'XVTRP'.
Again, when each letter is moved one step backward we get the code 'WUSQO'.
Hence, option (A) is the correct answer.
