Chemistry · Some Basic Concepts of Chemistry

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): During any physical change or chemical reaction in a closed system, the total mass of the system increases progressively. Reason (R): Matter can neither be created nor destroyed in chemical reactions, which forms the basis of the Law of Conservation of Mass. In the light of the above statements, choose the correct answer from the options given below:

1. Both (A) and (R) are true and (R) is the correct explanation of (A).
2. Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
3. (A) is true but (R) is false.
4. (A) is false but (R) is true.
