Which of the following plants possess hallucinogenic properties ?

Options

A. Erythroxylon coca
B. Atropa belladona
C. Datura stramonium
D. All of these

Answer

To determine which plants possess hallucinogenic properties, we need to analyze the options provided. Here’s a step-by-step breakdown:

### Step 1: Identify the Plants
We have three plants to consider:
1. Erythroxylon coca
2. Atropa belladonna
3. Datura stramonium

### Step 2: Understand the Compounds
Next, we need to know what compounds can be extracted from these plants:
- **Erythroxylon coca**: This plant is known for producing cocaine, which is a stimulant but not primarily known for hallucinogenic properties.
- **Atropa belladonna**: This plant contains atropine, which can have hallucinogenic effects.
- **Datura stramonium**: This plant also contains atropine and is known for its hallucinogenic effects.

### Step 3: Analyze Hallucinogenic Properties
Hallucinogenic properties refer to the ability of a substance to cause hallucinations, which are sensory experiences that appear real but are created by the mind. Both Atropa belladonna and Datura stramonium are known to cause such effects due to the presence of alkaloids.

### Step 4: Conclusion
Given that both Atropa belladonna and Datura stramonium are known for their hallucinogenic properties, and considering that Erythroxylon coca does not primarily cause hallucinations, we conclude that the correct answer is:
- **D. All of the above** (since the question implies that we are considering the hallucinogenic properties of the plants listed).

### Final Answer
The plants that possess hallucinogenic properties are:
**D. All of the above** (Erythroxylon coca, Atropa belladonna, and Datura stramonium).
