All of the following relationships are correct, except one. Determine the wrong answer and explain why the others are correct.

A) 5612 ~ 1475
B) 4657 ~ 1210
C) 4326 ~ 1080
D) 2474 ~ 755
E) 1781 ~ 737

These kinds of problems are always very tough because any kind of relation can be established.  It's always hard for me to divine the one that the poser had in mind.

For instance, the relation might be that the number of elements in each numbers' prime factorization is not less on the right.  This makes A the odd one out since 23, 61, 2, 2 (4 elements) is greater than 59, 5, 5 (3 elements) and all the rest are 1~5, 4~7, 2~2, and 2~2.
