For P-->Q: If you work hard(P) then you will qualify NET(Q).
For R-->S: If you play game(R) then you will get gold(S).
Given premise is PVR : means if u work hard(P) OR(v) if you play game(R), then conclusion will be-
than You will qualify NET(Q) OR(v) you will get gold(S). Which is nothing but QVS.
Hence, Option D is correct.
