Answer

To solve the question "Which of the following drug is obtained from the plant of genus Erythroxylum?", we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Options**: The options given are Marijuana, Hashish, Heroin, and Cocaine.

2. **Analyze Each Option**:
- **Marijuana**: This drug is derived from the Cannabis sativa plant, not from Erythroxylum. Therefore, it is not the correct answer.
- **Hashish**: Similar to marijuana, hashish is also obtained from the Cannabis plant. Hence, it is not the correct answer either.
- **Heroin**: This is an opioid drug that is synthesized from morphine, which is extracted from the opium poppy (Papaver somniferum). Thus, it does not come from Erythroxylum.
- **Cocaine**: This drug is an alkaloid obtained from the coca plant, specifically Erythroxylum coca. It is known for its stimulating effects on the central nervous system.

3. **Conclusion**: Based on the analysis, the drug obtained from the plant of genus Erythroxylum is Cocaine.
