If those are the only options, I guess I would take the swim. You have an outside chance with sharks, but no chance at all with the lava.
Choosing among the two, I will choose drink lava. From the characteristic of a lava, it cools faster than what we expected. Around 10 to 15 minutes, the lava that flows out from the mouth of the volcano cools immediately compared to what we expected. If you are in the middle of a shark infested pool, then, good luck.
