Assertion : The conjunctiva is thin, little cornified and richly supplied with free nerve endings.
Reason : Conjunctiva is composed of squamous epithelium and is continuous with the dermis that lines the eyelids.

Options

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

Explanation

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that the conjunctiva is thin, slightly cornified, and richly supplied with free nerve endings.
- This means that the conjunctiva, which is a membrane covering the eye, is not thick and has a certain level of keratinization (cornification) and has many nerve endings, making it sensitive.

2. **Understanding the Reason**:
- The reason provided states that the conjunctiva is composed of squamous epithelium and is continuous with the dermis that lines the eyelids.
- This indicates that the conjunctiva is made up of a type of epithelial tissue (squamous) and connects with the skin layer (dermis) of the eyelids.

3. **Analyzing the Structure of Conjunctiva**:
- The conjunctiva is indeed made up of stratified squamous epithelium, which is consistent with the assertion.
- It has three parts: palpebral (or tarsal), bulbar (or ocular), and fornix conjunctiva. The palpebral conjunctiva lines the eyelids, while the bulbar conjunctiva covers the eyeball.

4. **Evaluating the Assertion and Reason**:
- Since the conjunctiva is thin and has free nerve endings, the assertion is correct.
- The reason is also correct as it accurately describes the composition of the conjunctiva and its continuity with the dermis of the eyelids.

5. **Conclusion**:
- Both the assertion and the reason are correct, and the reason provides a correct explanation for the assertion. Therefore, the correct answer is that both statements are true, and the reason is the correct explanation of the assertion.

### Final Answer:
Both the assertion and the reason are correct, and the reason is the correct explanation of the assertion.
