The correct answer would be B. Since it is the only option that doesn't involve much physical activity.
Here's why:
Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory LUNG disease that causes obstructed airflow from the lungs. Symptoms include breathing difficulty, cough, mucus production and wheezing. Hence why doing extra curricular activities such as walking to the mailbox, climbing stairs, or grocery shopping would not be as easy for someone with COPD as reading a book would.
Hope this helps better explain! Good luck. :-)
<span>False. Muscular strength cannot
be achieved without muscular endurance. Both are health-related fitness
components that depend on each other. When muscles are able to endure bouts of physical
exertion, strength is developed; and in the same way that strength cannot be
fully achieved if endurance is poor. All athletes must include in their
training the development of both to last in their specific events or
competitions. It should be a gradual build-up of activities with strength
leaning to the other end of the training program. </span>
