If the fraction $$\frac{m}{n}$$ is negative, which of the following CANNOT be true?

A. $$\frac{n}{m}$$>$$\frac{m}{n}$$
This is also possible
B. mn < 0
one can be negative and other positive therefore the possibility exists

C. n – m > 0
n+vve and m-ve therefore possible

D. $$mn^3$$ > 0
Not possible since both cannot be positive or negative simultaneouslt therefore our option

E. m – n > 0m+ve and n-ve possible

Therefore IMO D
