Assertion : Glycine is amphoteric in nature .
Reason: Glycine contain both acid and basis group.

Options

A. If both assertion and reason are true and the reason is the correct explanation of the assertion.
B. If both assertion and reason are true but reason is not the corret explanation of the assertion.
C. If assertion is true but reason is false.
D. If the assertion and the reason both are false.

Explanation

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that glycine is amphoteric in nature. Amphoteric substances are those that can act as both acids and bases.

2. **Analyzing Glycine Structure**: Glycine is the simplest amino acid and has the chemical formula NH2CH2COOH. It contains both an amino group (-NH2) which can act as a base, and a carboxylic acid group (-COOH) which can act as an acid.

3. **Identifying Acidic and Basic Properties**:
- The **amino group (-NH2)** can accept a proton (H+), thus acting as a base.
- The **carboxylic acid group (-COOH)** can donate a proton (H+), thus acting as an acid.

4. **Conclusion about Glycine's Nature**: Since glycine has both acidic (carboxylic group) and basic (amino group) functionalities, it can react in ways that demonstrate both acidic and basic characteristics. Therefore, glycine is indeed amphoteric.

5. **Understanding the Reason**: The reason given states that glycine contains both acid and basic groups. This is true and directly supports the assertion that glycine is amphoteric.

6. **Final Evaluation**: Both the assertion and the reason are correct. The reason correctly explains why glycine is amphoteric.

### Final Answer:
Both the assertion and the reason are correct, and the reason correctly explains the assertion.
