If m – n > 3, then which of the following must be true?

I. m – n > 0
II. m*n > 0
III. m/n > 0

A. I only
B. II only
C. III only
D. I and III only
E. I, II and III
­I. m−n is always greater than zero since 3 is already greater than 0. So, statement I is true.

II. This statement doesn't necessarily hold true. If m and n have opposite signs (one positive and one negative), their product will be negative, not greater than zero. Thus, statement II is not necessarily true.

III. If m and n have the same sign (both positive or both negative), their division will be positive. However, if they have opposite signs, their division will be negative. So, statement III is not necessarily true.

Thus, Only (A) holds true....­
