Aperson will be able to perform these types of activities in their target heart rate zone for a long period of time. a. muscular strength b. cardio respiratory endurance c. flexibility d. sitting

Hey there!

It’s not flexibility or sitting because that’s not exercising. It would not be muscular strength because that can’t be maintained for a long time. It’s B. Cardio respiratory endurance. Endurance means that something lasts. A target heart rate zone needs to be held for 20 minutes. Running will help stay at a high enough heart rate zone.

I hope this helps!
