C. II and III are incorrect
D. III and IV are incorrect

Answer

To solve the question regarding the statements about morphine, we will evaluate each statement one by one to determine if they are correct or incorrect.

### Step-by-Step Solution:

1. **Evaluate Statement I**:
- **Statement**: "It is opioid drugs which binds to specific opioid receptors present in our brain and gastrointestinal tract."
- **Analysis**: This statement is correct. Opioid drugs, including morphine, do bind to specific opioid receptors located in the brain and gastrointestinal tract, which are involved in pain regulation and other functions.

2. **Evaluate Statement II**:
- **Statement**: "The chemical diacetylmorphine is called smack or heroine."
- **Analysis**: This statement is also correct. Diacetylmorphine is indeed commonly known as heroin or "smack."

3. **Evaluate Statement III**:
- **Statement**: "Heroin is obtained by acetylation of morphine, extracted from the latex of cannabis sativa plant."
- **Analysis**: This statement is incorrect. While it is true that heroin is obtained by the acetylation of morphine, morphine is derived from the latex of the opium poppy (Papaver somniferum), not from the cannabis sativa plant.

4. **Evaluate Statement IV**:
- **Statement**: "Heroin is a central nervous system stimulant and causes hallucination."
- **Analysis**: This statement is also incorrect. Heroin is a central nervous system depressant, not a stimulant, and while it can cause various effects, hallucinations are not a typical effect associated with heroin use.

### Conclusion:
- **Correct Statements**: I and II
- **Incorrect Statements**: III and IV

Based on the evaluations:
- The correct answer is that **statements III and IV are incorrect**.

### Final Answer:
The correct option is that statements III and IV are incorrect.
