Show Worked Solution

B is correct: A line graph effectively shows changes over time, which is essential for displaying heart rate recovery patterns after aerobic training.

Other Options:

A is incorrect: A pie chart is suitable for showing proportions within a whole, not for displaying physiological changes over time.
C is incorrect: A list of names and maximum heart rates doesn’t visually represent patterns or relationships in the data.
D is incorrect: A bar graph is better for comparing discrete categories rather than continuous changes over time that occur during recovery.
