In the following questions a statement of assertion followed by a statement of reason is given. Choose the correct answer out of the following choices.

Assertion : Penicillin(G) is an antihistamine.

Reason : Penicillin (G) is effective against gram positive as well as gram negative bacteria.

Both assertion and reason are wrong statement.

The correct answer is option 3. Both assertion and reason are wrong statement.

Let us break down why both the assertion and reason are incorrect statements:

Assertion: Penicillin (G) is an antihistamine

Penicillin G belongs to a class of medication called antibiotics. Antibiotics work by killing bacteria or stopping their growth.

Correct Function: Penicillin G specifically targets bacterial cell walls, a structure not present in human cells. This targeted action makes it effective against bacterial infections.

Antihistamines: These medications work by blocking the action of histamine, a chemical released by the body during an allergic reaction. Histamine causes allergy symptoms like runny nose, itchy eyes, and swelling.

Reason: Penicillin (G) is effective against gram positive as well as gram negative bacteria

Penicillin G is primarily effective against gram-positive bacteria.

Gram-Positive vs. Gram-Negative Bacteria: This classification refers to the structure of the bacteria's cell wall. Penicillin G disrupts the cell wall synthesis in gram-positive bacteria, making it ineffective against some gram-negative bacteria with an outer membrane offering additional protection.

Not Relevant to Antihistamines: The effectiveness against different types of bacteria is entirely unrelated to the function of antihistamines, which target human body chemistry, not bacterial cell walls.

In summary, Penicillin G is an antibiotic, not an antihistamine, and its effectiveness against bacteria doesn't explain its non-existent antihistamine properties.
