• A. increases; increases
• B. decreases; decreases
• C. decreases; increases
• D. increases; decreases

Answer: (C)

Verified step by step guidance

1. Understand the concept of Basal Metabolic Rate (BMR): BMR is the rate at which your body uses energy while at rest to maintain vital functions such as breathing and keeping warm.
2. Recognize the relationship between BMR and age: As people age, their BMR typically decreases because of a loss of muscle mass and other physiological changes.
3. Define the weight set point: This is the weight range in which your body is programmed to function optimally. It is influenced by genetics, hormones, and lifestyle factors.
4. Analyze the relationship between BMR and weight set point: When BMR decreases with age, the body may adjust its weight set point upwards to maintain energy balance, as the body becomes more efficient at using energy.
5. Conclude the relationship: Therefore, as BMR decreases with age, the weight set point tends to increase, which explains the correct answer choice 'decreases; increases'.
