Solution

The correct option is B Both A and R are true but R is not the correct explanation of A
Assertion and Reason both are correct and Reason is not correct explanation of Assertion. All naturally occurring $α -$ amino except glycine are optically active. Glycine is optically inactive because glycine does not have all four different substituent as shown below:
