Read the following statements and select the correct ones
(i) In simple cuboidal epithelium nuclei are rounded and lie in the centre of the cells.
(ii) Non - keratinized epithelium is impervious to water.
(iii) Yellow elastic fibrocartilage makes cartilage flexible.
(iv) Areolar tissue forms a shock absorbing cushion around the eye balls and kidneys.

Options

A. (i) and (iii)
B. (i) and (ii)
C. (iii) and (iv)
D. (ii) and (iv)

Answer

To solve the question, we will analyze each statement one by one to determine which ones are correct.

### Step-by-Step Solution:

1. **Statement (i)**: "In simple cuboidal epithelium nuclei are rounded and lie in the centre of the cells."
- **Analysis**: This statement is correct. In simple cuboidal epithelium, the cells are cube-shaped, and the nuclei are typically rounded and centrally located within the cells.

2. **Statement (ii)**: "Non-keratinized epithelium is impervious to water."
- **Analysis**: This statement is incorrect. Non-keratinized epithelium is not impervious to water; it allows for some permeability. In contrast, keratinized epithelium (like that found in the skin) is what is impervious to water.

3. **Statement (iii)**: "Yellow elastic fibrocartilage makes cartilage flexible."
- **Analysis**: This statement is correct. Yellow elastic fibrocartilage contains elastic fibers that provide flexibility, making it suitable for structures that require both strength and elasticity.

4. **Statement (iv)**: "Areolar tissue forms a shock absorbing cushion around the eyeballs and kidneys."
- **Analysis**: This statement is incorrect. Areolar tissue is a loose connective tissue that provides support and flexibility but does not specifically form a shock-absorbing cushion around the eyeballs and kidneys. Instead, it is adipose tissue that serves this function.

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

Thus, the correct option is **first and third**.
