Final answer:
Microbiology includes Epidemiology, which monitors disease spread, and Biotechnology, which applies organisms' metabolism for products. The correct option is (A).
Step-by-step explanation:
The question pertains to the disciplines within microbiology. Epidemiology is the branch of microbiology that involves the monitoring and control of the spread of disease through communities.
On the other hand, Biotechnology is the discipline that encompasses any process in which humans use the metabolism of organism to arrive at a desired product, such as using fermentation to produce antibiotics or using genetically engineered microbes for bioremediation to remove pollutants.
Therefore, the correct answer to the question is: A. Epidemiology; Biotechnology.
