The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Assertion**: The assertion states that "Broad spectrum antibiotics are produced by Streptomyces." This is true. Streptomyces is a genus of bacteria known for its ability to produce a wide variety of antibiotics, including broad-spectrum antibiotics that can target multiple types of bacteria. 2. **Understanding the Reason**: The reason provided is "They can destroy microorganisms by inhibiting DNA replication or protein synthesis." This is also true. Broad-spectrum antibiotics work by interfering with essential processes in bacteria, such as DNA replication and protein synthesis, which are crucial for bacterial growth and survival. 3. **Linking Assertion and Reason**: Both the assertion and the reason are correct statements. The assertion correctly identifies the source of broad-spectrum antibiotics (Streptomyces), while the reason explains the mechanism by which these antibiotics exert their effects on microorganisms. 4. **Conclusion**: Since both the assertion and the reason are true, and the reason explains why the assertion is true, we can conclude that the statement is valid. ### Final Answer: Both the assertion and the reason are correct, and the reason supports the assertion. ---

Assertion : Pencillin has a narrow spectrum. Reason : Antibiotics inhibit the growth or destroy micro-organisms.

Assertion (A) Preservative are added to food items. Reason (R) Preservatives inhibit the growth of microorganisms.

Passage 2 Antibiotics are the chemical substances which are produced by microorganisms like bacteria, fungi and moulds. Antibiotics can inhibit the growth or even destroy other microorganisms. Now-a-days, synthetic antibiotics are also available. The first successful antibiotic produced was penicillin. The antibiotics may be either bacteriocidal (kills the organism in the body) or bacteriostatic (inhibits the growth of organism). Ampicillin and amoxycillin are modified antibiotics. Broad spectrum antibiotics are effective against several types of harmful microorganisms. 2. Which of the following is/are not an antibiotic ?
