Expert Solution

Facultative anaerobes are organisms that can switch between aerobic and anaerobic types of metabolism. They can grow in both aerobic and anerobic conditions. Under anaerobic conditions, they grow by fermentation and in the aerobic conditions, they undergo aerobic respiration.

In the absence of oxygen, their growth rate will be explained by line b, but in the presence of oxygen, their growth rate will be shown by line a. So, the correct answer is option A.
