Answer

To determine the types of cancer from the given options, we need to analyze each option based on the definition and classification of cancer.

**Step 1: Understand what cancer is.**
Cancer is characterized by uncontrolled cell division and growth, leading to the formation of tumors or abnormal cell proliferation.

**Hint:** Remember that cancer involves uncontrolled growth of cells.

**Step 2: Evaluate each option.**
- **A. Sarcoma:** This is a type of cancer that arises from connective tissues such as bone, cartilage, fat, and muscle. Therefore, it is a type of cancer.

- **B. Leukemia:** This is a cancer of the blood-forming tissues, including the bone marrow and lymphatic system. It leads to the production of abnormal blood cells. Thus, it is also a type of cancer.

- **C. Gastric ulcer:** This is not a type of cancer. It refers to a sore on the lining of the stomach and is generally related to conditions like infection or the use of certain medications, not uncontrolled cell growth.

- **D. Lymphoma:** This is a type of cancer that originates in the lymphatic system, which is part of the immune system. Therefore, it is a type of cancer.

**Step 3: Identify the correct options.**
From the analysis:
- Sarcoma (A) is a type of cancer.
- Leukemia (B) is a type of cancer.
- Gastric ulcer (C) is NOT a type of cancer.
- Lymphoma (D) is a type of cancer.

Thus, the correct types of cancer from the options provided are A (Sarcoma), B (Leukemia), and D (Lymphoma).

**Final Answer:** The correct types of cancer are A (Sarcoma), B (Leukemia), and D (Lymphoma).
