Read the following statements about animal tissues and choose the option which correctly states true (T) or false (F ).
(1) Bone is the main tissue that provides a structural frame to the body.
(2) The intercellular material of cartilage is solid and non- pliable, which resists compressions.
(3) The ligament attached skeletal muscles to bones.
(4) In all connective tissue without exception, the cells secrete fibres of structural collagen or elastin proteins.

Options

A. 1 - F , 2 - T , 3 - F , 4 - T
B. 1 - T , 2 - F , 3 - T , 4 - T
C. 1 - F , 2 - T , 3 - T , 4 - F
D. 1 - T , 2 - F , 3 - F , 4 - F

Answer

To solve the question, we need to evaluate each of the four statements about animal tissues and determine whether they are true (T) or false (F).

### Step-by-Step Solution:

1. **Evaluate Statement 1:**
- **Statement:** "Bone is the main tissue that provides a structural frame to the body."
- **Analysis:** This statement is true. Bone is indeed the primary tissue that forms the skeletal structure of the body, providing support and protection for internal organs.
- **Conclusion:** True (T)

2. **Evaluate Statement 2:**
- **Statement:** "The intercellular material of cartilage is solid and non-pliable, which resists compressions."
- **Analysis:** This statement is false. While cartilage does resist compression, it is not entirely non-pliable; it has some flexibility compared to bone. Therefore, calling it "non-pliable" is misleading.
- **Conclusion:** False (F)

3. **Evaluate Statement 3:**
- **Statement:** "The ligament attaches skeletal muscles to bones."
- **Analysis:** This statement is false. Ligaments connect bones to other bones, while tendons are the connective tissues that attach muscles to bones.
- **Conclusion:** False (F)

4. **Evaluate Statement 4:**
- **Statement:** "In all connective tissue without exception, the cells secrete fibres of structural collagen or elastin proteins."
- **Analysis:** This statement is false. While many connective tissues do contain collagen and elastin fibers, blood is a type of connective tissue that does not have these fibers; its matrix is fluid (plasma).
- **Conclusion:** False (F)

### Final Results:
- Statement 1: True (T)
- Statement 2: False (F)
- Statement 3: False (F)
- Statement 4: False (F)

### Answer:
The correct option is:
- 1: T
- 2: F
- 3: F
- 4: F
