a. her muscular strength
b. her cardiovascular endurance
c. her flexibility
d. her body composition

Explanation:

To determine the correct answer, we analyze each option:

• Option A: Muscular strength refers to the ability of a muscle to exert force, which is not measured by jogging on a treadmill to assess heart and lung function.
• Option B: Cardiovascular endurance is the ability of the heart, lungs, and blood vessels to supply oxygen during sustained physical activity. Jogging for 10 minutes to assess heart and lung function aligns with measuring cardiovascular endurance.
• Option C: Flexibility is the range of motion in joints, and jogging on a treadmill does not primarily measure flexibility.
• Option D: Body composition refers to the proportion of fat, muscle, bone, etc., in the body, which is not measured by this treadmill jogging test for heart and lung function.

Answer:

B. her cardiovascular endurance
