Microbiology is the study of microbes as we study about microorganisms and there parts and the disease

and in a way they are synonyms as well so C is the correct answer

Microbiology is the study of Microbes.

Explanation:
Microbiology is a branch of science that deals with the study of microorganisms, which are tiny, unicellular organisms that are too small to be seen with the naked eye. These microorganisms include bacteria, viruses, fungi, algae, and protozoa. Microbes are found everywhere such as in soil, water, air, and even inside the human body. The study of microbiology involves the following:

1. Identification of microorganisms: Microbiologists study the physical, chemical, and genetic characteristics of microorganisms to identify and classify them.

2. Microbial biochemistry: Microbes play an important role in the production of useful products such as antibiotics, enzymes, and vaccines. This branch of microbiology studies the biochemical processes that occur in microorganisms.

3. Microbial genetics: Microorganisms have a unique genetic makeup that allows them to adapt and survive in different environments. Microbial genetics studies the structure and function of genes in microorganisms.

4. Microbial ecology: Microbes are important in the ecosystem and play a vital role in the cycling of nutrients. Microbial ecology studies the interactions between microorganisms and their environment.

5. Microbial pathogenesis: Some microorganisms cause diseases in humans, animals, and plants. Microbial pathogenesis studies the mechanisms by which microorganisms cause disease and how the immune system responds to them.

In conclusion, microbiology is a broad field that encompasses the study of all aspects of microorganisms, from their structure and function to their role in the ecosystem and in human health and disease.
