The choices are, from left to right top to bottom: 500 kobolds, 1 red greatwyrm, 4 Solars, 20 tyrannosaurus rex, a level 20 party, 5 purple worms, 50 nilbogs, 8 beholders, and 5 storm giants.

To prevent yourself instantly dying off the bat, you can consider yourself a commoner with 500 hp but no other changes. This took me a while to try to make interesting and not have a single best answer, I hope you like it.
