## Core Concept
The question tests the understanding of pharmacological properties of various drugs, specifically their potential for dependence. **Dependence** refers to a state where an individual experiences withdrawal symptoms upon cessation of the drug or a significant reduction in its dosage.
## Why the Correct Answer is Right
Chlorpromazine is a **first-generation (typical) antipsychotic** primarily used in the treatment of schizophrenia. It works by blocking dopamine receptors in the brain, which helps in reducing psychotic symptoms. Unlike opioids, benzodiazepines, and certain other classes of drugs known for their high potential for dependence, chlorpromazine does not typically cause dependence, although it can have side effects like **tardive dyskinesia** with long-term use.
## Why Each Wrong Option is Incorrect
- **Option A:** This option is not provided, but generally, substances like morphine are known for their high potential for dependence.
- **Option B:** This option is also not provided, but drugs like alprazolam (a benzodiazepine) are well-known for their dependence potential.
- **Option D:** Similarly, this option is not specified, but drugs like nicotine are highly addictive and cause significant dependence.
## Clinical Pearl / High-Yield Fact
A key point to remember is that while chlorpromazine itself is not commonly associated with dependence, **antipsychotic discontinuation** can sometimes lead to withdrawal symptoms, and abrupt cessation, especially after long-term use, may require gradual tapering.
## Correct Answer: C. Chlorpromazine
