Read the following statements about animal tissues : A. The smooth muscle muscle fibres are non-striated, fusioform shape and hold together by cell junctions.
B. Cardiac muscle is structurally similar to smooth muscle and acts similar to skeletal muscle.
C.The skeletal muscle is the only multinucleate and voluntary muscles with alternate light and dark striations .

Options

A. A and B are correct , C is incorrect
B. A is incorrect, B and C are correct
C. A and C are correct , B is incorrect
D. A is correct , B and C are incorrect

Answer

To solve the question regarding the statements about animal tissues, we will analyze each statement one by one.

### Step 1: Analyze Statement A
**Statement A:** "The smooth muscle fibers are non-striated, fusiform shape and held together by cell junctions."

- **Analysis:** Smooth muscle fibers are indeed non-striated, meaning they do not have the alternating light and dark bands that characterize striated muscles. They are also fusiform in shape, which means they are spindle-shaped. Additionally, smooth muscle fibers are connected by cell junctions known as gap junctions, which allow for coordinated contractions.

- **Conclusion:** Statement A is **correct**.

### Step 2: Analyze Statement B
**Statement B:** "Cardiac muscle is structurally similar to smooth muscle and acts similar to skeletal muscle."

- **Analysis:** Cardiac muscle is actually structurally similar to skeletal muscle because both are striated. They contain myofibrils and have a similar arrangement of actin and myosin filaments. Functionally, cardiac muscle is more similar to smooth muscle in that both are involuntary. Therefore, this statement incorrectly describes the structural relationship between cardiac and smooth muscle.

- **Conclusion:** Statement B is **incorrect**.

### Step 3: Analyze Statement C
**Statement C:** "The skeletal muscle is the only multinucleate and voluntary muscle with alternate light and dark striations."

- **Analysis:** Skeletal muscle is indeed multinucleate, meaning it has multiple nuclei per cell. It is also voluntary, as it is under conscious control. Additionally, skeletal muscle exhibits striations, which are the alternating light and dark bands due to the arrangement of myofibrils. Therefore, this statement is accurate.

- **Conclusion:** Statement C is **correct**.

### Final Conclusion
Based on the analysis:
- Statement A is correct.
- Statement B is incorrect.
- Statement C is correct.

Thus, the correct option is that **A and C are correct, and B is incorrect**.
