Options

A. benign tumours show the property of metastasis
B. heroine accelerates body functions
C. malignant tumours may exhibit metastasis
D. patients who have undergone surgery are give cannabinoids to relieve pain

Answer

To determine which statement is correct, we need to analyze each option provided in the question.

### Step-by-Step Solution:

1. **Analyze Option A: "Benign tumors show the property of metastasis."**
- Benign tumors are non-cancerous and do not spread to other parts of the body. They remain localized and do not exhibit metastasis, which is the process of cancer spreading. Therefore, this statement is **incorrect**.

2. **Analyze Option B: "Heroin accelerates body function."**
- Heroin is an opioid that depresses the central nervous system rather than accelerating body functions. It can lead to sedation and decreased respiratory function. Thus, this statement is also **incorrect**.

3. **Analyze Option C: "Malignant Tumor May Exhibit Metastasis."**
- Malignant tumors are cancerous and have the potential to spread to other parts of the body through metastasis. However, the use of the word "may" implies that it is not guaranteed, which is misleading. While malignant tumors can metastasize, not all do. Therefore, this statement is **incorrect**.

4. **Analyze Option D: "Patients who have undergone surgery are given cannabinoids to relieve pain."**
- Cannabinoids, such as those found in medical marijuana, can be used to relieve pain in patients, including those who have undergone surgery. Morphine is a separate pain management drug, but cannabinoids are indeed used for pain relief. Therefore, this statement is **correct**.

### Conclusion:
The correct answer is **Option D: Patients who have undergone surgery are given cannabinoids to relieve pain.**
