Even though alexandra could talk with her friends during dance class, she couldn't sing along to the songs. which best describes her heart rate during this
activity?
a) low
b) moderate
c) vigorous
d) dangerous

Option C, Vigorous

Explanation:

Dancing is a vigorous form of exercise in which the breathing rate increases at a very fast pace.

Talking or singing while doing any vigorous exercise leads to further loss of energy and weak breathing pattern.

If Alexandra starts singing along with breathing, then she would not be able to perform dance efficiently for a long period of time.

Hence, option C is correct.
