Most of the antibiotices are obtained from

Options

A. Actinomycetes
B. Eubacteria
C. Ray fungi
D. Both (1) and (2)

Answer

### Step-by-Step Solution:

1. **Understanding Antibiotics**: Antibiotics are substances that help to fight bacterial infections. They are crucial in medicine for treating various bacterial diseases.

2. **Sources of Antibiotics**: The primary sources of antibiotics are microorganisms, particularly certain types of bacteria and fungi.

3. **Actinomycetes**: A significant group of bacteria known for producing antibiotics is the actinomycetes. Among these, the genus *Streptomyces* is particularly important as it produces many clinically valuable antibiotics.

4. **Examples of Antibiotics**: Some well-known antibiotics derived from *Streptomyces* include streptomycin, erythromycin, and chloramphenicol. These antibiotics are effective against various bacterial infections.

5. **Eubacteria**: Besides actinomycetes, eubacteria (true bacteria) also contribute to antibiotic production. They are a diverse group of bacteria that can produce various bioactive compounds.

6. **Ray Fungi**: Ray fungi (or fungi in general) are not typically used to produce antibiotics for treating bacterial infections. While some fungi do produce antibiotics (like penicillin from *Penicillium*), the question specifies that most antibiotics come from actinomycetes and eubacteria.

7. **Conclusion**: Therefore, the correct answer to the question is that most antibiotics are obtained from actinomycetes and eubacteria.

### Final Answer:
Most of the antibiotics are obtained from actinomycetes and eubacteria.
