Answer

To solve the question of selecting the correct match from the provided options, we will analyze each statement carefully.

### Step-by-Step Solution:

1. **Understanding Therapsids**:
- Therapsids are indeed a group of synapsids that are considered ancestors of mammals. They existed during the late Permian to the Triassic periods and are known for their evolutionary significance in the lineage leading to mammals.
- **Conclusion**: This statement is correct.

2. **Analyzing Icthyosaur**:
- The statement claims that Icthyosaur was a big fearsome dinosaur. However, Icthyosaurs were marine reptiles, not dinosaurs. They lived during the Mesozoic era and are distinct from dinosaurs, which were primarily terrestrial.
- **Conclusion**: This statement is incorrect.

3. **Examining Homo habilis**:
- The claim that Homo habilis was the first to use fire and eat meat is misleading. While Homo habilis is one of the earliest known human ancestors, there is no substantial evidence that they used fire or had a diet primarily consisting of meat. They likely consumed fruits and other plant materials.
- **Conclusion**: This statement is incorrect.

4. **Reviewing Homo erectus**:
- The assertion that Homo erectus was the first man to use stone tools and is called handyman is inaccurate. While Homo erectus did use tools, the term "handyman" is often associated with Homo habilis, who is known for making simple stone tools. Homo erectus is recognized for more advanced tool use and has a larger cranial capacity.
- **Conclusion**: This statement is incorrect.

### Final Decision:
Based on the analysis of the statements:
- The only correct match is **Option A**: Therapsids are the ancestors of mammals.
