Assertion : cellulose is a homopolymer while chitin is a heteroploymer
gt Reason : cellulose is made up of identical monomers while chitin is made up of variable monomer units.

Options

A. If both assertion & Reason are ture & the Reason is a correct explanation of the Assertion
B. If both Assertion & Reason ar True but Reason is not a correct explantation of the Assertion
C. If Assertion is True but the Reason is False
D. If both Assertion & Reason are false

Answer

### Step-by-Step Solution:

1. **Understanding the Terms**:
- **Homopolymer**: A polymer made up of identical monomer units.
- **Heteropolymer**: A polymer made up of different types of monomer units.

2. **Analyzing the Assertion**:
- The assertion states that "cellulose is a homopolymer while chitin is a heteropolymer."
- Cellulose is indeed a homopolymer as it is made up of repeating units of glucose.
- However, chitin is also a homopolymer because it is primarily composed of N-acetylglucosamine, which is a derivative of glucose.

3. **Analyzing the Reason**:
- The reason states that "cellulose is made up of identical monomers while chitin is made up of variable monomer units."
- While cellulose is made up of identical glucose monomers, chitin does not consist of variable monomer units; it is made up of the same type of monomer (N-acetylglucosamine).

4. **Conclusion**:
- Both the assertion and the reason are incorrect.
- Therefore, the correct answer is that both the assertion and reason are false.

### Final Answer:
Both assertion and reason are false.
