C. Ramapithecus `to` Homo habilis `to` Homo erectus Homo sapiens
D. Australopithecus `to` Ramapithecus `to` Homo erectu `to` Homo habilis `to` Homo sapiens.

Answer

**Step-by-Step Solution:**

1. **Understanding Human Evolution**: Human evolution is a complex process that traces the development of modern humans from earlier species. It involves several key stages and species.

2. **Starting Point - Ramapithecus**: The earliest known ancestor in the human lineage is Ramapithecus, which appeared approximately 14 to 15 million years ago. This species is considered one of the earliest members of the human lineage.

3. **Transition to Homo habilis**: Following Ramapithecus, the next significant species in the evolutionary line is Homo habilis. This species emerged around 2 million years ago and is often referred to as one of the first members of the genus Homo.

4. **Evolution to Homo erectus**: From Homo habilis, the lineage progresses to Homo erectus. This species is known for its more advanced tools and is believed to have existed from about 1.9 million years ago to as recently as 110,000 years ago.

5. **Arrival of Homo sapiens**: The final stage in this evolutionary line is Homo sapiens, which is the species name for modern humans. Homo sapiens appeared approximately 200,000 to 300,000 years ago and are characterized by advanced cognitive abilities and complex social structures.

6. **Conclusion**: The most accepted line of descent in human evolution is from Ramapithecus to Homo habilis, then to Homo erectus, and finally to Homo sapiens.

**Final Answer**: The most accepted line of descent in human evolution is Ramapithecus → Homo habilis → Homo erectus → Homo sapiens.
