A: Intercellular material is minimum between the cells of epithelial tissue.
R: Epithelial cells are not secretory in nature.

Options

A. Cartilage
B. Ligament
C. Areolar tissue
D. Bone

Answer

**Step-by-Step Solution:**

1. **Understanding the Assertion (A)**: The assertion states that "Intercellular material is minimum between the cells of epithelial tissue." This means that the space between the cells in epithelial tissue is very small, indicating that the cells are closely packed together.

2. **Analyzing the Reason (R)**: The reason given is that "Epithelial cells are not secretory in nature." This implies that if epithelial cells do not secrete substances, there might be less intercellular material.

3. **Evaluating the Truth of the Assertion**: Epithelial tissues are indeed characterized by closely packed cells with minimal intercellular material. This is true because epithelial tissues serve as protective layers and have a compact structure.

4. **Evaluating the Truth of the Reason**: The statement that "Epithelial cells are not secretory in nature" is false. In fact, many epithelial cells are involved in secretion. For example, glandular epithelium is specialized for secretion, producing substances like hormones, enzymes, and mucus.

5. **Conclusion**: Since the assertion is true (A is true) and the reason is false (R is false), we conclude that the correct relationship is that the assertion is true, but the reason is not valid.

**Final Answer**: Assertion (A) is true, and Reason (R) is false.
