When the digits of two-digit, positive integer M are reversed, the result is the two-digit, positive integer N. If M > N, what is the value of M?

(1) The integer (M - N) has 12 unique factors.

(2) The integer (M - N) is a multiple of 9.

This is a question from VERITAS, I did not understand their explanation.
1. Why 90 is not considered.
2. Why 96 is rejected.
Can someone please explain in detail?
