Options

A. Dryopithecus
B. Ramapithecus
C. Homo habilis
D. Homo erectus

Explanation

To identify the name of the first ancestral man among the given options, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Options**: We have four options to consider:
- A) Dryophithecus
- B) Remaphithecus
- C) Homo habilis
- D) Homo erectus

2. **Analyze Each Option**:
- **Dryophithecus**: This is an extinct genus of apes that lived during the Miocene epoch, but it is not considered the first ancestral man.
- **Remaphithecus**: This genus is significant as it is considered one of the earliest primates and is dated back to the middle or late Miocene epoch, approximately 16.6 million years ago.
- **Homo habilis**: This species is known as one of the earliest members of the genus Homo, living around 2.4 to 1.4 million years ago, but it is not the first ancestral man.
- **Homo erectus**: This species appeared later than Homo habilis and is known for being one of the first to use fire and have a more advanced tool culture.

3. **Determine the First Ancestral Man**: Based on the analysis, Remaphithecus is the earliest primate listed among the options and is considered the first ancestral man.

4. **Conclusion**: Therefore, the correct answer is **B) Remaphithecus**.
