Explanation:

Step1: Analyze each option

• Option 1: A 10 - year - old's heart rate is not shown on the graph, and there is no indication that it is the same as a 20 - year - old's.
• Option 2: From the graph, a 20 - year - old and a 30 - year - old both have an average resting heart rate of 72 beats per minute.
• Option 3: A 40 - year - old has the same heart rate (72) as a 50 - year - old, so it may have the same rate for ten years.
• Option 4: For teenagers (age 0 - 20), the heart rate steadily decreases from 112 to 72.
