Assertion. Bithional is added to soap for its beautification and solidification.
Reason. Bithional is a sulpha drug.

Options

A. If both assertion and reason are true, and reason is the true explanation of the assertion.
B. If both assertion and reason are true, but reason is not the true explanation of the assertion.
C. If assertion is true, but reason is false
D. If both assertion and reason are false.

Explanation

To analyze the given assertion and reason, we will break down the components step by step.

### Step 1: Understanding the Assertion
The assertion states that "Bithional is added to soap for its beautification and solidification."

- **Analysis**: Bithional is a compound known for its antiseptic properties. It is often used in soaps and other personal care products, but its primary function is not beautification or solidification. Instead, it is used to enhance the antibacterial properties of the soap.

### Step 2: Understanding the Reason
The reason states that "Bithional is a sulpha drug."

- **Analysis**: Bithional is indeed related to sulphonamides, which are a class of drugs known as sulpha drugs. These drugs are primarily used for their antibacterial properties. However, the classification of Bithional as a sulpha drug does not directly support the assertion regarding beautification and solidification.

### Step 3: Evaluating the Relationship
Now, we need to evaluate the relationship between the assertion and the reason.

- **Conclusion**: The assertion is incorrect because Bithional is not added to soap for beautification and solidification; it is added for its antiseptic properties. The reason is correct in stating that Bithional is a sulpha drug, but it does not justify the assertion. Therefore, both the assertion and reason are not true in relation to each other.

### Final Answer
Both the assertion and the reason are incorrect in the context provided. Thus, the correct option would be that neither the assertion nor the reason is true.
