B. Hepatitis A&E
C. Cancer
D. AIDS and Cancer

Answer

### Step-by-Step Solution:

1. **Understanding Non-Infectious Diseases**:
- Non-infectious diseases are those that are not caused by pathogens (bacteria, viruses, etc.) and do not spread from person to person through physical contact. Examples include cancer, diabetes, and heart diseases.

2. **Analyzing the Options**:
- The options provided are AIDS, hepatitis A and E, cancer, and a combination of AIDS and cancer.
- We need to determine which of these is a non-infectious disease and a major cause of death.

3. **Evaluating Each Option**:
- **AIDS**: While AIDS is not caused by a pathogen in the traditional sense, it is a contagious disease transmitted through specific physical contact (e.g., unprotected sex, sharing needles). Therefore, it is not classified as non-infectious.
- **Hepatitis A and E**: These are viral infections that affect the liver and can be transmitted through contaminated food and water. They are infectious diseases, not non-infectious.
- **Cancer**: Cancer is a non-infectious disease that arises from genetic mutations, environmental factors, and lifestyle choices. It is a leading cause of death worldwide due to its complexity and late diagnosis.
- **AIDS and Cancer**: This option includes AIDS, which we have already established is not non-infectious.

4. **Conclusion**:
- Among the options, cancer is the only non-infectious disease listed and is recognized as a major cause of death globally. Therefore, the answer to the question is **cancer**.

### Final Answer:
The major cause of death among non-infectious diseases is **cancer**.
