The brutal way is to go one condition after another.

1) If you remove both h and s, could you still find 3 person out of the other 5?  If yes, this is not the answer.

Alternatively, you can check the answers you already get from #18-21 to knock off some choices from #22.

Lastly, both A and D are definitely out, as h/s and m/p cannot both be in.
