D. none of the above

Answer

**Step-by-Step Solution:**

1. **Understanding Homo erectus**: Homo erectus is an important species in human evolution, known for its upright walking posture. It is a part of the lineage that leads to modern humans.

2. **Evolutionary Context**: The evolutionary timeline includes several species leading up to Homo erectus, such as Dryopithecus, Ramapithecus, Australopithecus, and Homo habilis. Each of these species shows an increase in brain capacity over time.

3. **Cranial Capacity of Ancestors**:
- Australopithecus had a cranial capacity of about 500 cc (cubic centimeters).
- Homo habilis had a larger cranial capacity than Australopithecus.

4. **Cranial Capacity of Homo erectus**: Homo erectus is known to have a cranial capacity ranging from approximately 800 cc to 1100 cc. This increase in cranial capacity is significant in the context of human evolution.

5. **Analyzing Options**:
- The options provided are:
- 650 to 800 cc (incorrect)
- 900 cc (correct)
- 1400 cc (incorrect)
- Based on the information, the correct answer regarding the brain capacity of Homo erectus is 900 cc.

6. **Conclusion**: Therefore, the brain capacity of Homo erectus is about 900 cc.
