Answer: (B)

Verified step by step guidance

1. Identify the key term in the question: 'primary focus of microbiology.' This means understanding what microbiology mainly studies.
2. Recall the definition of microbiology: it is the branch of biology that deals with microorganisms, which are organisms too small to be seen with the naked eye.
3. Evaluate each option by comparing it to the definition of microbiology:
4. - 'The study of the structure and function of human tissues' relates more to histology or anatomy.
5. - 'The study of organisms too small to be seen without a microscope' matches the definition of microbiology.
6. - 'The study of animal behavior in natural environments' is the focus of ethology or behavioral ecology.
7. - 'The study of chemical reactions in living organisms' pertains to biochemistry.
8. Therefore, the best description of microbiology is the study of organisms too small to be seen without a microscope.
