it is E.

we need to know the vaule of x and y for this solution

from statement i and ii we get positive or negative value of x and y.

so E is the answer.

Simplifying the stem we get:

Is xy>x^4y?

1. Two values for x --->Insuff.
2. Two values for y --->Insuff.

Together the question can be answered either (yes) or (no).

(E)
