b. 5 minutes to warm up, 25 minutes of aerobic activity, 0 minutes to cool down
c. 0 minutes to warm up, 15 minutes of aerobic activity, and 15 minutes to cool down
d. 5 minutes to warm up, 20 minutes of aerobic activity, 5 minutes to cool down

Explanation:

A proper aerobic exercise plan should include a warm - up to prepare the body, a sufficient amount of aerobic activity, and a cool - down to help the body recover. Option A has a long warm - up and cool - down but relatively short aerobic activity. Option B has no cool - down, which is not good for recovery. Option C has no warm - up, which can lead to injury. Option D has a 5 - minute warm - up (to prepare the body), 20 minutes of aerobic activity (a reasonable duration), and 5 minutes of cool - down (to help the body recover gradually), which follows the best practices for an aerobic exercise plan.

Answer:

D. 5 minutes to warm up, 20 minutes of aerobic activity, 5 minutes to cool down
