पर्याय

• Both A and R are true and R is the correct explanation of A.

• Both A and R are true but R is not the correct explanation of A.

• A is true but R is false.

• A is false but R is true.

Answer 1

A is false but R is true.

Explanation:

A triatomic molecule contains three atoms, not four, so A is false. A monoatomic molecule contains one atom, so R is true; however, R does not explain the incorrect assertion.
