Answer 2

Complete question:

Assertion (A): Bacteria and fungi are used to make medicines.

Reason (R)​: These medicines are used to cure viral diseases.

Read the statements and choose the correct option below

1. Assertion (A) is true, and Reason (R) is the correct explanation of Assertion (A).

2. Assertion (A) is true, Reason (R) is not the correct explanation of Assertion (A).

3. Both statements are false.

4. Assertion (A) is true, but the Reason (R) is false.

Answer:

4. Assertion (A) is true, but the Reason (R) is false.

Explanation:

• Antibiotics (chemical substances) are a range of powerful medications which are produced by some microbes and can kill or check the growth of other (disease-causing) microbes.

• "Anti" is a Greek word that means 'against', and bio means 'life', together they mean 'against life' (in the context of disease-causing organisms-pathogens) whereas concerning human beings, they are 'pro life' and not against.
• Thus Assertion (A) is true and correct.

• Antibiotics produced by microbes such as bacteria and fungi are considered to be one of the most significant discoveries of the 20th century and have greatly contributed to the welfare of human society.  

• Antibiotics damage the cell wall of disease-causing organisms leading to their death.

• Viruses are different to bacteria they have different structures and a different ways of surviving.

• The viruses lack a cell wall. Antibiotics produced by bacteria and fungi are effective against bacterial infections, and not viral infections because viruses use host cells to perform their activities.
• Hence, they cannot kill viruses. That's why antibiotics are not effective against viral diseases.

• Since viral diseases are non-responsive to antibiotics, the reason (R) is thus false.        

Therefore, option 4. Assertion (A) is true, but the Reason (R) is false is the correct answer.
