Assertion (A) All naturally occurring `alpha`-aminoacids except glycine are optically active.
Reason (R) Most naturally occurring amino acids have L-configuration.

Options

A. Assertion and reason both are correct statements and reason explains the assertion.
B. Both assertion and reason are wrong statements
C. Assertion is correct statement and reason is wrong statement.
D. Assertion and reason both are correct statement but reason does not explain assertion.

Explanation

To analyze the given assertion and reason, we will break down the statements and provide a step-by-step solution.

### Step-by-Step Solution:

1. **Understanding the Assertion (A)**:
- The assertion states that "All naturally occurring alpha-amino acids except glycine are optically active."
- To determine if this is true, we need to understand what makes an amino acid optically active. An amino acid is optically active if it has a chiral carbon atom, which means it has four different groups attached to it.
