Read the following statements `(i-iv)` and accordingly
mark the option that has both statements .
The Cardiac fiber are brandhed with one or more nuclei.
The Striated muscles can be branched or unbranched
The Involuntary muscles are non-striated
The Smooth muscles are unbranched and cylindrical

Options

A. ` i and iii`
B. ` ii and iv`
C. ` ii and iii`
D. ` i and ii`

Answer

To solve the question, we need to analyze each of the provided statements about muscle types and identify which two statements are correct.

### Step-by-Step Solution:

1. **Evaluate Statement (i)**: "The Cardiac fibers are branched with one or more nuclei."
- **Analysis**: Cardiac muscle fibers are indeed branched and typically contain one or two nuclei. This statement is **correct**.

2. **Evaluate Statement (ii)**: "The Striated muscles can be branched or unbranched."
- **Analysis**: Striated muscles, also known as skeletal muscles, are primarily unbranched. They are arranged in parallel bundles and do not branch. This statement is **incorrect**.

3. **Evaluate Statement (iii)**: "The Involuntary muscles are non-striated."
- **Analysis**: Involuntary muscles, such as smooth muscles, do not have a striated appearance. This statement is **correct**.

4. **Evaluate Statement (iv)**: "The Smooth muscles are unbranched and cylindrical."
- **Analysis**: Smooth muscles are indeed unbranched, but they are not cylindrical; they have a fusiform shape (thick in the middle and tapering at the ends). This statement is **incorrect**.

### Conclusion:
Based on the evaluations:
- Correct Statements: (i) and (iii)
- Incorrect Statements: (ii) and (iv)

Thus, the option that contains both correct statements is **(i) and (iii)**.

### Final Answer:
The correct option is **A** (i and iii).
