## **Core Concept**
The question pertains to a specific adverse drug reaction (ADR) associated with a particular class of medications. Understanding the pharmacological profiles of the listed options is crucial to identifying the correct answer. The ADR in question seems to be related to a well-known side effect of certain drugs.

## **Why the Correct Answer is Right**
Option is associated with **hepatotoxicity** or liver damage, which is a well-documented adverse drug reaction. This class of drugs can cause an elevation in liver enzymes, indicating liver stress or damage. The mechanism often involves the formation of toxic metabolites that damage liver cells.

## **Why Each Wrong Option is Incorrect**
- **Option A:** This option is incorrect because it is not commonly associated with the specific ADR of hepatotoxicity to the same extent as option .
- **Option B:** This option does not directly correlate with hepatotoxicity as a primary ADR; it may have other side effects but is not the best match for the given ADR.
- **Option C:** Although this option might have various side effects, it is not primarily known for causing hepatotoxicity.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that **isoniazid**, a first-line antitubercular medication, is known for its potential to cause hepatotoxicity. Monitoring liver function tests is a crucial part of managing patients on this medication. This association is a high-yield fact for exams.

## **Correct Answer:** .
