## **Core Concept**
The question tests the understanding of which poisons can be removed from the body through dialysis, a process known as hemodialysis. Dialyzable poisons are typically substances that are water-soluble, have a low molecular weight, and are not extensively bound to plasma proteins or tissues.

## **Why the Correct Answer is Right**
. is not dialyzable because it has a high lipid solubility and is extensively stored in body tissues, making it less accessible for removal through dialysis. This characteristic makes it difficult to remove through hemodialysis.

## **Why Each Wrong Option is Incorrect**
* **Option A:** is dialyzable due to its pharmacokinetic properties that allow it to be effectively removed through hemodialysis.
* **Option B:** is also dialyzable because it meets the criteria for substances that can be removed through dialysis, such as low molecular weight and water solubility.
* **Option C:** can be dialyzed as it has properties that make it amenable to removal through this method.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that the effectiveness of dialysis in removing a poison depends on the substance's molecular weight, protein binding, and volume of distribution. Substances with a high volume of distribution (like ) or those that are highly lipid-soluble tend to be less dialyzable.

## **Correct Answer:** .
