C. If A is true and R is false
D. If both A and R are false

Answer

### Step-by-Step Solution:

1. **Understanding the Structure of Conjunctiva**:
- The conjunctiva is a thin, transparent membrane that covers the inner surface of the eyelids and the white part of the eyeball (sclera). It is composed of non-keratinized stratified squamous epithelium.

**Hint**: Remember that the conjunctiva is not thick; it is a delicate layer that plays a protective role.

2. **Function of the Conjunctiva**:
- The conjunctiva secretes mucus, which helps keep the eye moist and provides a barrier against pathogens. This secretion is crucial for maintaining eye health and comfort.

**Hint**: Think about how mucus functions in protecting and lubricating surfaces in the body.

3. **Conjunctivitis**:
- If the conjunctiva becomes inflamed due to infection or irritation, the condition is known as conjunctivitis. This inflammation can lead to redness, swelling, and discharge from the eye.

**Hint**: Conjunctivitis is often associated with symptoms like redness and discomfort in the eye.

4. **Thickness of the Conjunctiva**:
- The statement that the conjunctiva is "thick" is incorrect. The conjunctiva is actually a thin layer of tissue, which is important for its function in protecting the eye while allowing light to pass through.

**Hint**: Consider the importance of transparency in the conjunctiva's role in vision.

5. **Conclusion**:
- The first part of the statement regarding the composition of the conjunctiva is correct, while the assertion that it is thick is false. Therefore, the correct interpretation of the statements is that the first statement is true, and the second statement is false.

**Hint**: Always evaluate each part of a statement separately to determine its truthfulness.
