Which of the following are the reasons for the occurrence of multi-drug resistance in microbial pathogens in India?<br/>1. Genetic predisposition of some people<br/>2. Taking incorrect doses of antibiotics to cure diseases<br/>3. Using antibiotics in livestock farming<br/>4. Multiple chronic diseases in some people<br/><br/>Select the correct answer using the code given below.

1. Genetic predisposition of some people — Multi-drug resistance arises mainly due to selection pressure on microbes, not because some humans are genetically predisposed. Verdict: Incorrect.

2. Taking incorrect doses of antibiotics to cure diseases — Incomplete/incorrect antibiotic use allows surviving microbes to develop and spread resistance. Verdict: Correct.

3. Using antibiotics in livestock farming — Antibiotic use in animals promotes resistant strains that can enter humans through food, environment, or contact. Verdict: Correct.

4. Multiple chronic diseases in some people — Chronic diseases may increase susceptibility to infection, but they are not a primary reason for the emergence of microbial multi-drug resistance. Verdict: Incorrect.

Hence, only 2 and 3 are correct. Answer: (b).
