**Core Concept**
DDT (Dichlorodiphenyltrichloroethane) is a synthetic insecticide that acts on the nervous system of insects by disrupting the normal function of the sodium channel, leading to hyperexcitability and death. It belongs to the class of organochlorine pesticides.

**Why the Correct Answer is Right**
DDT works by binding to the sodium channel in the nerve axon, which prevents the normal influx of sodium ions and disrupts the action potential. This action is highly specific to the insect nervous system, making DDT a potent insecticide. The sodium channel is an essential component of the neuronal membrane, responsible for the rapid depolarization phase of the action potential.

**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect because DDT is indeed a synthetic insecticide.
**Option B:** Incorrect because DDT does disrupt the normal function of the sodium channel in the insect nervous system, but the statement might be too vague or incomplete.
**Option C:** Incorrect because this statement is actually true - DDT is a well-known example of an organochlorine pesticide.

**Clinical Pearl / High-Yield Fact**
It's essential to remember that DDT has been linked to various environmental and health concerns, including bioaccumulation and neurotoxic effects. Its use has been largely phased out in many countries due to these risks.

**Correct Answer: C. DDT is a well-known example of an organochlorine pesticide.**
