B. Cytoplasm
C. Nucleus
D. None of these

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the name of a dense spherical body located at the center of the cell.

2. **Analyzing the Options**:
- **Option 1: Cell Wall**: The cell wall is a protective outer layer found in plant cells, but it is not located at the center of the cell. Therefore, this option is incorrect.
- **Option 2: Cytoplasm**: Cytoplasm is the jelly-like substance within the cell where various cellular processes occur. However, it is not a dense spherical body and is not located at the center. Hence, this option is also incorrect.
- **Option 3: Nucleus**: The nucleus is a dense, spherical structure found at the center of the cell. It contains the cell's genetic material and controls many cellular activities. This option is correct.
- **Option 4: None of these**: Since we have already identified the nucleus as the correct answer, this option is incorrect.
