D. Limnopithecus.

Explanation

To solve the question about the earliest and most primitive anthropoid ape during the Oligocene epoch, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Terms**:
- The term "anthropoid" refers to a group of primates that includes monkeys, apes, and humans.
- The "Oligocene" is a geological epoch that lasted from about 34 to 23 million years ago.

2. **Identify the Options**:
- The options provided are:
- A) Parapithecus

- C) Proconsul
- D) Limnopithecus

3. **Analyze Each Option**:
- **Parapithecus**: This is known to be one of the earliest anthropoid apes and is believed to have lived during the Oligocene epoch.
- **Propliopithecus**: This ape lived later, around the Miocene epoch, making it incorrect for the Oligocene.
- **Proconsul**: This genus is also from the Miocene epoch and is known to be an ancestor of modern chimpanzees and gorillas, thus not fitting the Oligocene timeframe.
- **Limnopithecus**: This genus is associated with gibbons and also dates back to the Miocene epoch, making it incorrect for the Oligocene.

4. **Conclusion**:
- Based on the analysis, the earliest and most primitive anthropoid ape during the Oligocene is **Parapithecus**.

### Final Answer:
- The correct answer is **A) Parapithecus**.
