Options

A. Nutrition related diseases
B. pathogen related diseases
C. Genetic disorders
D. Degeneration diseases

Answer

**Step-by-Step Text Solution:**

1. **Understanding Koch's Postulates**: Koch's postulates are a set of criteria established by the scientist Robert Koch to determine whether a specific microbe is the cause of a specific disease.

2. **Identifying the Criteria**: There are four main postulates:
- The microorganism must be found in abundance in all organisms suffering from the disease, but should not be found in healthy organisms.
- The microorganism must be isolated from a diseased organism and grown in pure culture.
- The cultured microorganism should cause disease when introduced into a healthy organism.
- The microorganism must be re-isolated from the inoculated, diseased experimental host and identified as being identical to the original specific causative agent.

3. **Focus on Pathogen-Related Diseases**: These postulates specifically relate to pathogens (microbes) and their role in causing diseases. They do not pertain to nutritional diseases, genetic disorders, or degenerative diseases.

4. **Conclusion**: Based on the criteria outlined in Koch's postulates, the correct answer to the question is **b. Pathogen related diseases**.
