The correct Answer is:
To determine the correct statements from the given options, let's analyze each statement one by one: 1. **Statement (i)**: "In simple cuboidal epithelium, nuclei are rounded and lie in the centre of the cells." - **Analysis**: Simple cuboidal epithelium is characterized by cube-shaped cells where the nuclei are indeed rounded and typically located centrally within the cells. - **Conclusion**: This statement is **correct**. 2. **Statement (ii)**: "Non-keratinized epithelium is impermeable to water." - **Analysis**: Non-keratinized epithelium is not impermeable to water; it allows for some permeability. In contrast, keratinized epithelium is the type that is impermeable to water due to the presence of keratin. - **Conclusion**: This statement is **incorrect**. 3. **Statement (iii)**: "Yellow elastic fibrocartilage makes cartilage flexible." - **Analysis**: Yellow elastic fibrocartilage contains elastic fibers that provide flexibility to the cartilage. This type of cartilage is indeed known for its flexibility, which is essential for certain structures in the body. - **Conclusion**: This statement is **correct**. 4. **Statement (iv)**: "Areolar tissue forms a shock absorbing cushion around the eyeballs and kidneys." - **Analysis**: While areolar tissue provides support and elasticity, it is actually adipose tissue that forms a shock-absorbing cushion around the eyeballs and kidneys, not areolar tissue. - **Conclusion**: This statement is **incorrect**. ### Summary of Correct Statements: - **Correct Statements**: (i) and (iii) - **Incorrect Statements**: (ii) and (iv) ### Final Answer: The correct options are **(i)** and **(iii)**. ---
