Assertion (A): Minerals such as coal, petroleum and natural gas are organic substances found in solid, liquid and gaseous forms.

Reason (R): Coal, petroleum and natural gas are found in sedimentary rocks.

विकल्प

• Both A and R are true and R is the correct reason for A.

• Both A and R are true but R is not the correct reason for A.

• A is true and R is false.

• A is false and R is true.

Answer 1

Both A and R are true and R is the correct reason for A.

Explanation:

Coal (solid), petroleum (liquid), and natural gas (gaseous) are organic minerals formed from ancient biological matter. They are primarily found in sedimentary rock formations, which act as reservoirs for these fossil fuels. Thus, the presence of these organic minerals in sedimentary rocks explains their occurrence in solid, liquid, and gaseous states.
