Final answer:
The situation that meets a criterion for inferring causality between exercise and adaptation behavior of women receiving chemotherapy for breast cancer is when the level of adaptation behaviors increases in proportion to the intensity of the exercise.
Step-by-step explanation:
The situation that meets a criterion for inferring causality between performance of exercise and adaptation behavior of women receiving chemotherapy for breast cancer is option c. The level of adaptation behaviors increasing proportionately with the increase in the intensity of the exercise.
When the level of adaptation behaviors increases in proportion to the intensity of the exercise, it suggests a direct relationship between exercise and adaptation behavior. This indicates that the exercise is causing the adaptation behavior in women receiving chemotherapy for breast cancer.
For example, if women who engage in high-intensity exercise show a greater increase in adaptation behaviors compared to women who engage in low-intensity exercise, it suggests that the exercise is causing the adaptation behavior.
