The answer is letter B.
Poor aerobic capacity can
make it difficult to perform certain activities that involve aerobic threshold.
Examples of these exercises are brisk walking for 30 minutes, running for 20-30 minutes, or playing badminton.
Aerobic capacity refers to
the ability of the cardiorespiratory system to work together in synchronicity
in able to supply the body with the enough oxygen it needs to perform muscle
contractions. This process happens through the circulatory system when the
blood flows from the heart to the lungs and into the different parts of the
body. Having a poor aerobic capacity means that the cardiorespiratory and
circulatory systems are not efficiently working together leading to poor
performance in different activities.
