Which one fo the following population interactions is widely used in medical science for the production of antibiotics?

Options

A. Parasitism
B. Mutualism
C. Commensalism
D. Amensalism

Explanation

**Step-by-Step Solution:**

1. **Understanding Population Interactions**: In ecology, different species interact with each other in various ways. These interactions can be categorized based on their effects on the organisms involved.

2. **Identifying the Types of Interactions**: The main types of interactions include:
- Mutualism: Both species benefit.
- Commensalism: One species benefits while the other is unaffected.
- Parasitism: One species benefits at the expense of the other.
- Competition: Both species are harmed due to competition for resources.
- Amensalism: One species is harmed while the other is unaffected.

3. **Focusing on Medical Science and Antibiotics**: The question specifically asks about interactions that are relevant to the production of antibiotics in medical science.

4. **Recognizing the Role of Fungi in Antibiotic Production**: The first antibiotic, penicillin, was discovered to be produced by the fungus Penicillium. This fungus produces substances that inhibit the growth of bacteria.

5. **Defining Amensalism**: In the context of antibiotic production, we see that the Penicillium fungus produces a compound that kills bacteria (which are harmful to humans), while the fungus itself remains unaffected. This is a classic example of amensalism, where one organism is harmed (the bacteria) and the other is neutral (the fungus).

6. **Conclusion**: Based on the analysis, the correct answer to the question is that the population interaction widely used in medical science for the production of antibiotics is **Amensalism**.

**Final Answer**: Amensalism
