In jar B, the candle remains lighted for a longer time because oxygen is a supporter of combustion. So, we can say that oxygen ( is necessary for combustion to take place.

The glass jar which is filled with oxygen gas will support the burning of the candle for a longer time.
As we know that the base requirements for a fire to be produced are:-
1) Fuel
2) Ignition temperature
3) Oxygen
Here,
The fuel is the candle's wax. The Ignition temperature has already been supplied (Since, The candle is burning already). And, The second jar is supplying the 3rd and the last requirement for the candle to be lighted.
While, The 1st jar is not supplying Oxygen but at its place Carbon dioxide. So, The candle will not remain lighted for long in the 1st jar.
Hope this helps you!
