Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R. Assertion A : A solution of the product obtained by heating a mole of glycine with a mole of chlorine in presence of red phosphorous generates chiral carbon atom. Reason R : A molecule with 2 chiral carbons is always optically active. In the light of the above statements, choose the correct answer from the options given below:

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

Correct answer: A is true but R is false
