Solution

The correct option is D
Candle burns more brightly

Oxygen gas is colourless, odourless, and tasteless gas. Hence, you can't smell or taste or see to test the presence of oxygen.

But if you take a candle flame and you notice that it burns brighter and stronger, you can be sure it's oxygen.
