In dense regular connective tissue -

Options

A. fibres are loosely packed
B. Fibres are tightly packed
C. Bundles of fibres run parallel
D. Both b and c

Answer

To answer the question about dense regular connective tissue, we will analyze the characteristics of this type of tissue step by step.

### Step-by-Step Solution:

1. **Understanding Dense Regular Connective Tissue**:
- Dense regular connective tissue is a type of connective tissue that is characterized by its high tensile strength and the arrangement of its fibers.

2. **Fiber Arrangement**:
- In dense regular connective tissue, the collagen fibers are arranged in parallel bundles. This parallel arrangement allows the tissue to withstand pulling forces in one direction.

3. **Fiber Packing**:
- The collagen fibers in dense regular connective tissue are tightly packed together. This tight packing provides strength and support to the tissue.

4. **Options Analysis**:
- **Option A**: "Fibers are loosely packed." - This is incorrect because the fibers are tightly packed.
- **Option B**: "Fibers are tightly packed." - This is correct.
- **Option C**: "Bundles of fibers run parallel." - This is also correct.
- **Option D**: "Both B and C options are correct." - Since both B and C are correct, this option is also correct.

5. **Conclusion**:
- The correct answer to the question is option D, which states that both B and C are correct.

### Final Answer:
The correct answer is **Option D: Both B and C are correct**.
