If y>x>0, which of the following must be true:
I. x^2>y^2
II. x^3 > y^3
III. |x|<y	Choose the most appropriate option
A) I only  B) II only  C) III only  D) II and III  E) I, II and III
Assuming x and y to be integers   X=3,Y=2   X^2=3^2=9   Y^2=2^2=4   So I is true   Now lets look at option III because if option 3 is true E is the answer or else A   As per question X&gt;Y&gt;0 Hence |X| &gt;Y   So OA=III only
<result>C</result>
If y>x>0, which of the following must be true:
