Solution

The correct option is A Soil contains moisture.
Soil contains air, water, minerals and organic matter. The moisture in the soil is nothing but the water content of the soil. Priya's inference should be that the soil taken by her contains moisture as tiny water droplets are appearing on the wall of the boiling tube.
