The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Ageing**: Ageing is a natural process that affects various physiological functions in the body. It is characterized by gradual changes in the body's systems and structures. 2. **Analyzing the Options**: - **Decrease in cholesterol level**: Generally, cholesterol levels can increase with age due to dietary habits and metabolic changes, so this option is unlikely to be correct. - **Increase in calcium contents of arteries and cartilage**: This is also not true. With ageing, there is typically a decrease in calcium levels in these tissues. - **Decrease in calcium contents of arteries and cartilage**: This option aligns with the biological understanding of ageing. As individuals age, the calcium content in arteries and cartilage tends to decrease, which can lead to various health issues. - **Decrease in blood urea**: Blood urea levels can fluctuate with age, but there is no consistent evidence to suggest that they decrease with ageing. 3. **Conclusion**: Based on the analysis of the options, the most accurate statement regarding ageing is that there is a decrease in calcium contents of arteries and cartilage. 4. **Final Answer**: The correct option is **decrease in calcium contents of arteries and cartilage**. ---
