Solution
The correct option is C NADREG
Explanation:
SYSTEM → SYSMET
4th and 6th letters are interchanged. 1st and 3rd letters may or may not have been interchanged, but cannot be determined.
From the options, only options B and C have followed the above condition (interchanging 4th and 6th letters).
But in option B, instead of interchanging 1st and 3rd letters, the 1st letter is moved to 3rd position and 2nd letter becomes the 1st letter and the 3rd letter becomes the 2nd letter.
So, only option C can be the right answer.
