(C) $$15 < xy < 88$$

(D) $$24 < xy < 55$$

(E) $$33 < xy < 40$$

Now from the inequality we see that minimum value of x > 3 and minimum value of y >5

Hence the minimum value of xy > 15

Similarly we see that maximum value of x < 8 and minimum value of y < 11

Hence the minimum value of xy < 88

So only option C fulfills the inequality i.e $$15 < xy < 88$$
