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:
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 is false but $R$ is true
- Both $A$ and $R$ are true and $R$ is the correct explanation of $A$
- A is true but $R$ is false
- Both $A$ and $R$ are true but $R$ is not the correct explanation of $A$
The Correct Option is B
Solution and Explanation
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

Top JEE Main Questions
- Two masses $m$ and $\frac{m}{2}$ are connected at the two ends of a massless rigid rod of length $l$. The rod is suspended by a thin wire of torsional constant $k$ at the centre of mass of the rod-mass system(see figure). Because of torsional constant $k$, the restoring torque is $\tau =k\theta$ for angular displacement $\theta$. If the rod is rota ted by $\theta_0$ and released, the tension in it when it passes through its mean position will be:

Chemistry in Everyday Life
The scientific study of matter’s properties and behaviour is known as chemistry. It is a natural science that studies the elements that makeup matter, as well as the compounds, made up of atoms, molecules, and ions: their composition, structure, qualities, and behaviour, as well as the changes that occur when they mix with other things.
- Importance of Chemistry in Food - Chemicals are the fundamental components of everything. Chemical molecules make up all food, including carbs, vitamins, lipids, proteins, and fibre, which are all safe and often desirable.
- Importance of Chemistry in Medicines - Medicines or pharmaceuticals are chemical substances that are used to treat diseases and relieve pain. Chemistry has made significant contributions to health care. Chemistry, for example, aids in the manufacture and application of surgical materials.
- Importance of Chemistry in Cosmetics - In our daily lives, we use lotions, fragrances, talcum powder, and a variety of other cosmetic goods. All of these items are developed in laboratories using chemicals for our health and skin.
- Importance of Chemistry in Soaps and Detergents - Soaps are sodium and potassium salts of fatty acids with greater molecular weights, such as stearic acid, palmitic acid, and oleic acid. Sodium salts of long-chain alkyl hydrogen sulphates or sodium salts of long-chain alkyl benzene sulphonic acids are commonly used as detergents.
