D. 4

Answer

To determine the number of ova produced by a primary oocyte, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Primary Oocyte**: A primary oocyte is a diploid cell that undergoes meiosis to produce gametes (ova).

2. **Meiosis Process**: The primary oocyte undergoes meiosis, which consists of two stages: meiosis I and meiosis II.

3. **Meiosis I**:
- During meiosis I, the primary oocyte divides into two cells:
- One is a secondary oocyte (which will eventually become the ovum).
- The other is a polar body, which is a smaller cell that typically does not develop into a functional gamete.

4. **Meiosis II**:
- The secondary oocyte then undergoes meiosis II:
- It divides again, producing one ovum and another polar body.
- The polar body produced during meiosis II may also divide, but it does not contribute to the formation of a functional ovum.

5. **Final Count**:
- From one primary oocyte, we end up with:
- 1 functional ovum
- 3 polar bodies (1 from meiosis I and 2 from meiosis II)

6. **Conclusion**: Therefore, the number of ova produced from one primary oocyte is **1**.

### Final Answer:
The number of ova produced by a primary oocyte is **1**.
