My answer is b

Explanation:

here it says n is not equal to 0 but it doesnt mean that n is an integer.

from 1) m can by sqrt2 and n can be 1 or sqrt2 which means m/n is not necessary an integer so its insuff

from 2) m-n=0, but its possible that both m and n are not integers, however in any case since both m and n are equal, hence m/n=1, which is an integer so it b.
