**Core Concept**
Dhatura seeds resemble other edible seeds, which can sometimes lead to accidental ingestion. This resemblance can result in a diagnosis of anticholinergic toxicity due to the seeds' content of scopolamine and hyoscyamine.

**Why the Correct Answer is Right**
Dhatura seeds contain tropane alkaloids, specifically scopolamine and hyoscyamine, which are responsible for their anticholinergic effects. These compounds inhibit the action of acetylcholine at muscarinic receptors in the central and peripheral nervous system, leading to symptoms such as delirium, hallucinations, and tachycardia. The resemblance of Dhatura seeds to edible seeds like those of the Jimsonweed (Datura stramonium) or Deadly Nightshade (Atropa belladonna) can lead to accidental ingestion and subsequent toxicity.

**Why Each Wrong Option is Incorrect**
* **Option A:**
This option is likely incorrect, as there is no clear association between the seed of this plant and anticholinergic toxicity.
* **Option B:**
This option may be tempting, but it is not a correct comparison, as the seeds of this plant do not resemble Dhatura seeds.
* **Option C:**
This option is incorrect, as it does not accurately describe the resemblance of Dhatura seeds to other seeds.

**Clinical Pearl / High-Yield Fact**
When considering a diagnosis of anticholinergic toxicity, it is essential to ask about any potential exposure to plants with tropane alkaloids, such as Dhatura or Deadly Nightshade. A high index of suspicion and a thorough history are crucial in making this diagnosis.

**Correct Answer: D.**
