Which of the following causes Prostate cancer ?

Options

A. Chromium
B. Cadmium oxide
C. Vinyl chloride
D. Aflatoxins

Explanation

**Step-by-Step Solution:**

1. **Understanding Prostate Cancer**: Prostate cancer is characterized by the uncontrolled growth of cells in the prostate gland. It is essential to recognize that cancer involves the abnormal proliferation of undifferentiated cells.

2. **Identifying Carcinogens**: Carcinogens are agents that can lead to cancer. They can be physical (like gamma rays and x-rays) or chemical agents.

3. **Analyzing the Options**: The question provides several options, and we need to determine which of these is specifically linked to prostate cancer.

4. **Evaluating Each Option**:
- **Chromium**: While chromium is a carcinogen, it is primarily associated with gastrointestinal tract cancers, not prostate cancer.
- **Cadmium Oxide**: This is the correct answer, as cadmium oxide is known to be linked to prostate cancer.
- **Vinyl Chloride**: This chemical is associated with liver cancer, not prostate cancer.
- **Aflatoxin**: Similar to vinyl chloride, aflatoxins are also linked to liver cancer.

5. **Conclusion**: Based on the evaluation, cadmium oxide is the chemical agent responsible for causing prostate cancer.

**Final Answer**: Cadmium oxide (Option 2) is the cause of prostate cancer.
