Since fire is a chemical reaction, and oxygen is needed for that reaction, having a fire in a cave is a sure sign of the presence of oxygen.

The burning of the torch shows the presence of oxygen.

Combustion reaction is a reaction in which a substance burns in oxygen to produce heat and light. The process of combustion is exothermic.

A torch functions by combustion. Combustion reactions can only occur in the presence of oxygen.

Hence, if you are going into a cave and you carry a torch, the torch will keep burning if oxygen is present in the cave. If not, the torch will be extinguished.
