Correct Answer: (d) Air is present everywhere but not in soil.

Explanation:  Air is omnipresent in nature, hence, it is present everywhere including the soil. This can be proved by a simple activity:

  1. Take a lump of dry soil is taken in a beaker or a glass.
  2. Add water to it.

Observation: When water is added to the soil, it displaces the air which is seen in the form of bubbles.

Hence proved that air is present in the soil.
