If a and b are positive integers and a/b=0 then which of the following give positive Numbers and CANNOT be zero?	Choose the correct choice from the following choices:
A) ab/ba B) a/b-b/a C) b/a-a/b D) (a^2 -b^2)/ab E) a/b
(D) (a^2 -b^2)/ab = a/b-b/a gives negative value.   The option C is Answer.   (b/a-a/b)a/b-b/a   If a/b=0, b/a gives positive numbers.(a and b are positive integers)
