Probably list B, but only for the water purifying pills.
Problems with list A - I have little knowledge of medication, so it would be risky to use anything that I'm not 100% sure about. Besides, I doubt many people would run into a t-rex or group of velociraptors and live to tell the tale anyway. Hunting rifle is useless unless you seriously know how to fire a weapon. Besides, most dinos are too big to carry around after you've killed them, yet if you use the knife to cut off little bits, you'll probably be caught halfway through the act by some carnivorous critters due to the scent of blood.
Problems with list B - Making a fire is useless because the smoke will be seen at day, and the light will be seen at night. If you light a fire somewhere safe and concealed where neither will be seen, then the smoke will become a problem for
you. I guess choking to death is a bit nicer than being eaten by scary dinos, though. Still, this is the best group of items as the water purifying pills would be essential.
Problems with list C - Whilst a machete is probably more useful than an axe/knife, this list has nothing medically useful. If you're thinking of using the rope, use it as a noose and hang yourself with it as it's an easier way of committing suicide. Using the rope to climb up trees is all well and good, but when you're up there, what are you going to do? The climb down is an eventuality and you'll probably have to face a few hungry dinos who saw you go up and are waiting for you to come down. Oh, and tyrannosaurs are as big as trees. Using the rope to navigate cliffs just renders you as pterodactyl fodder. The SAS survival guide is also less useful than one might think - it does not take into account that the jungle you're in is home to a bunch of dinosaurs looking to eat you.
Oh, a problem with all three lists - don't forget that dinos are too big to carry around, so what are you going to do for food? Abandoned vending machine contents won't last forever, and even if they did, you'd just die of malnutrition.
So whichever one you choose, you're going to become lunch at some point.
