**Core Concept**
Hoffman's elimination is a chemical reaction in which an organic compound undergoes a process of de-amination, resulting in the removal of an amino group (-NH2). This reaction is crucial in understanding various biological processes, including neurotransmitter metabolism and the breakdown of amino acids.

**Why the Correct Answer is Right**
Hoffman's elimination involves the removal of an amino group from an organic compound, typically resulting in the formation of a new compound and the release of ammonia (NH3). This reaction is mediated by enzymes such as aromatic L-amino acid decarboxylase (AADC) and is an essential mechanism for the breakdown of amino acids and neurotransmitters like dopamine, norepinephrine, and serotonin. The correct answer involves the identification of a compound that undergoes Hoffman's elimination, which is often seen in the context of neurotransmitter metabolism.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not accurately describe a compound that undergoes Hoffman's elimination.
**Option B:** This option is incorrect because it is not directly related to Hoffman's elimination, which involves the removal of an amino group from an organic compound.
**Option C:** This option is incorrect because it is not a compound that undergoes Hoffman's elimination.

**Clinical Pearl / High-Yield Fact**
Hoffman's elimination is an essential mechanism for the breakdown of neurotransmitters, and its dysfunction can lead to various neurological disorders. For example, defects in the AADC enzyme can result in dopamine deficiency, leading to conditions like Parkinson's disease.

**Correct Answer:** C.
