(E)

Explanation:

#y>=0# looks like:

graph{y>=0 [-10, 10, -5, 5]}

#y<=x# looks like:

graph{y<=x [-10, 10, -5, 5]}

We can already rule to (A).

Since #y>=2# looks like:

graph{y>=2 [-10, 10, -5, 5]}

We can rule (C) out.

Also, since #x>=0# looks like:

graph{x>=0 [-10, 10, -5, 5]}

and #y>=x# looks like:

graph{y>=x [-10, 10, -5, 5]}

We can rule out (B).

So the answer has to be (D) or (E). You could have arrived to the same conclusion by observing that the shaded region is enclosed by 3 lines NOT 2.

Finally, since (D) and (E) are the same except for if #y>=2# or #y<=2#.

It's clear that #y>=2# is the correct inequality so (E) is the right answer.
