Question

If all the plants of the world die all the animals will also die due to shortage of

• A. Oxygen
• B. Timber
• C. Food
• D. Cold air

Answer 1

The correct option is A Oxygen

Oxygen is the primary source of living without which life is not possible. Water is also the main source of living. Food and timber are important for the living but if not consumed or used for a few days it will not cause death. If a person stops breathing for some time he will surely die.

So, the correct option is 'Oxygen'.
