E. C is an easy trap as we can easily assume that QR = X.

from i and ii, we know that "PQ = x + 2" and "PR = y = x + 3" but we do not know whether QR is x or not. QR can be anything between 1 and (2x=5) excluding as under:
x + 3 - (x +2) < QR < x + 3 + x + 2
1 < QR < 2x + 5

DS, rephrase --> They're asking which side of the triangle PQR is the longest.

A,B and D are out since either statement alone is insuff

If we combine A & B, then PQ=4 and PR=5. Which means QR has a range of 2-8 (based on law of triangle that the sum of any two sides must be greater than the third).

So you can't determine which angle is the greatest.
I like E

What's OA & OE & your explanation?
