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): Constituents of a heterogeneous mixture can often be separated using simple physical methods such as filtration or hand-picking. Reason (R): In any mixture, the constituent particles always combine chemically in a fixed, definite mass ratio. 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.
