Question

There are holes below the chimney of an oil lamp:

• A. to supply oxygen for burning the oil
• B. to let the smoke escape
• C. to increase the brightness of the lamp
• D. None of these

Answer 1

Answer: (A)

to supply oxygen for burning the oil

Oxygen is a supporter of combustion. In its absence, the oil cannot burn. So, holes are provided at the bottom of the lamp to ensure a continuous supply of oxygen to allow the oil to burn.

Hence, option $A$ is correct.
