The answer is c: stress management.
Explanation for each option:
a. Low cholesterol: While maintaining low cholesterol is important for cardiovascular health, it is not typically categorized as one of the three priority healthy lifestyles. It is more of a specific health goal rather than a broad lifestyle category.
b. Low blood pressure: Similar to low cholesterol, maintaining low blood pressure is crucial for health, but it is not generally considered one of the primary lifestyle categories. It is an outcome that can be influenced by healthy lifestyle choices.
c. Stress management: This is a key component of a healthy lifestyle. Managing stress effectively can have a significant impact on overall health and well-being, making it a priority alongside regular physical activity and sound nutrition.
d. Normal body weight: While maintaining a normal body weight is important, it is often a result of engaging in regular physical activity and sound nutrition rather than a separate lifestyle category.
In summary, stress management is considered one of the three priority healthy lifestyles, along with regular physical activity and sound nutrition.
