Answer: (D)

Verified step by step guidance

1. Understand the concept of homeostasis: Homeostasis refers to the body's ability to maintain a stable internal environment despite changes in external conditions. It involves various physiological processes that balance inputs and outputs to keep conditions within a narrow range.
2. Differentiate between primary, secondary, and tertiary prevention: Primary prevention aims to prevent the onset of disease before it occurs, secondary prevention focuses on early detection and intervention to prevent progression, and tertiary prevention involves managing disease to prevent further deterioration.
3. Identify examples of primary prevention: Eating a balanced diet, vaccination, and regular exercise are examples of primary prevention as they aim to prevent the onset of diseases or health issues.
4. Recognize secondary prevention: Screening for high blood pressure is an example of secondary prevention. It involves detecting a condition early to prevent complications, such as heart disease or stroke, by managing the condition effectively.
5. Apply the concept to the problem: In the context of maintaining homeostasis, secondary prevention like screening for high blood pressure helps in early detection and management, thereby preventing complications and maintaining the body's stable internal environment.
