Explanation:

Correct option 3: 46:12167

The logic here is: The last term is cube root of a number. That number is subtracted by 2 and this number is added to the last term to get the first term of each row.
So, 14:512=>512 = 8³, 8+ (8-2) = 14
22:1728 => 1728= 12³, 12+ (12-2) = 22
46:23=> 12167 = 23³, 23+ (23-2) = 44, But they have given 46 as the 1st term
38: 8000 => 8000= 20³, 20+ (20-2) = 38
Thus, all except option 3 does not follow the pattern.
Hence, the number pair '46: 12167' is the odd one out.
