Assertion : Newer Antibiotics are required to be prosuced Regularly .
Reason : Pathogens often develop resistance to existing antibiotics.

Options

A. If both Assertion and Reason are true and the reason is the correct explanation of the assertion , then mark (1) .
B. If both Assertion and Reason are true but the reason is not the correct explanation of the assertion , then mark (2).
C. If assertion is true but Reason is false , then false , then mark(3).
D. If both assertion is true Reason are false , then Mark (4).

Answer

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that "newer antibiotics are required to be produced regularly." This implies that there is a continuous need for the development of new antibiotics.

2. **Understanding the Reason**: The reason provided is that "pathogens often develop resistance to existing antibiotics." This indicates that bacteria (pathogens) can adapt and become resistant to the antibiotics currently available.

3. **Connection Between Assertion and Reason**: The assertion and reason are connected. If pathogens develop resistance to existing antibiotics, it follows that new antibiotics must be developed to effectively treat infections caused by these resistant strains.

4. **Explaining Antibiotic Resistance**: Antibiotic resistance occurs when bacteria evolve mechanisms to withstand the effects of drugs that once killed them or inhibited their growth. This is often facilitated by genetic elements like plasmids, which can carry resistance genes.

5. **Conclusion**: Both the assertion and reason are correct. The assertion is supported by the reason, as the need for newer antibiotics arises directly from the ability of pathogens to develop resistance to existing treatments.

6. **Final Answer**: Both statements are correct, and the reason is a correct explanation of the assertion.
