Answer

To solve the question, we will analyze each statement provided and determine which one is correct.

### Step-by-Step Solution:

1. **Evaluate Statement A**: "Patients who had undergone surgery are given cannabinoids to relieve pain."
- Cannabinoids are not typically used for post-surgical pain relief; instead, opioids like morphine are commonly prescribed. Cannabinoids can have stimulating effects, which may not be ideal for patients recovering from surgery.
- **Conclusion**: This statement is incorrect.

2. **Evaluate Statement B**: "Benign tumors show property of metastasis."
- Benign tumors are non-cancerous and do not spread to other parts of the body. Metastasis refers to the spread of cancer cells from the original tumor to other organs or tissues.
- **Conclusion**: This statement is incorrect.

3. **Evaluate Statement C**: "Heroin accelerates body function."
- Heroin is an opioid that depresses the central nervous system, leading to a slowing down of bodily functions rather than an acceleration. It is known for its sedative effects.
- **Conclusion**: This statement is incorrect.

4. **Evaluate Statement D**: "Malignant tumors may exhibit metastasis property."
- Malignant tumors are cancerous and have the ability to invade nearby tissues and spread to other parts of the body through the bloodstream or lymphatic system. This characteristic is what distinguishes malignant tumors from benign tumors.
- **Conclusion**: This statement is correct.

### Final Answer:
The correct statement is **D: Malignant tumors may exhibit metastasis property.**
