Explanation:

We do not know the directions in which they are sitting.
From statement I, there are two possibilities as
A B _ _ _ / _ _ _ B A
From statement II, we have
D C _ _ _ / _ D C _ _ / _ _ DC _ / _ _ _ D C
If we combine both statements, we get
A B D C _ / A B _ D C
OR
D C _ B A / _ D C B A
Now from statement I, E cannot be at corner
so we are left with A B _ D C and D C _ B A
now whatever the arrangement is, E is at middle.
