Question

Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason $R$
Assertion A : Antihistamines do not affect the secretion of acid in stomach
Reason R : Antiallergic and antacid drugs work on different receptors
In the light of the above statements, choose the correct answer from the options given below:

• A. A is false but $R$ is true
• B. Both $A$ and $R$ are true and $R$ is the correct explanation of $A$
• C. A is true but $R$ is false
• D. Both $A$ and $R$ are true but $R$ is not the correct explanation of $A$

Answer 1

Answer: (B)

Both $A$ and $R$ are true and $R$ is the correct explanation of $A$

Answer 2

Assertion A is true, stating that antihistamines do not affect the secretion of acid in the stomach.
Reason R is also true and provides the correct explanation. It states that antiallergic and antacid drugs work on different receptors. This explains why antihistamines, which are antiallergic drugs, do not impact stomach acid secretion, which is affected by antacid drugs that target different receptors.
Antiallergic and antacid drugs work on different receptors.
So, the correct answer is (B): Both A and R are true and R is the correct explanation of A
