a
b
c
d

Explanation:

Cardiovascular fitness is related to the heart (cardio) and blood vessels (vascular). It focuses on the body's ability to transport oxygenated blood efficiently as the heart and blood vessels work together to supply oxygen - rich blood to the body's tissues during physical activity. Option A is more about muscular endurance. Option C is about fat metabolism which is not the core of cardiovascular fitness. Option D is about energy conversion from sugar which is more related to cellular metabolism rather than the cardiovascular system's main function in fitness.

Answer:

B. the ability of the body to transport oxygenated blood efficiently
