A. Muscles
B. Cells
C. Inorganic salts
D. Cartilaginous membrane

Answer

**Step-by-Step Solution:**

1. **Understanding Tumors**: A tumor is defined as an abnormal mass that forms when cells grow and divide uncontrollably. This abnormal growth can lead to the formation of a lump or mass in the body.

2. **Types of Tumors**: Tumors can be classified into two main types based on their behavior:
- **Benign Tumors**: These are non-cancerous tumors that do not spread to other parts of the body. They usually grow slowly and can often be removed surgically.
- **Malignant Tumors**: These are cancerous tumors that can invade nearby tissues and spread to other parts of the body through the bloodstream or lymphatic system.

3. **Analyzing the Options**: The question provides four options:
- Option 1: Muscles
- Option 2: Cells
- Option 3: Inorganic salts
- Option 4: Cartilaginous membrane

4. **Identifying the Correct Answer**: Since a tumor is formed due to the abnormal proliferation of cells, the correct answer is:
- **Option 2: Cells**. The other options (muscles, inorganic salts, and cartilaginous membrane) do not represent the composition of a tumor.

5. **Conclusion**: Therefore, the final answer to the question "Tumor is an abnormal mass of" is **cells**.
