To determine which two species are grouped together on a phylogenetic tree, we need to consider their evolutionary relationships.
1. **Frog** - Frogs are amphibians.
2. **Coelacanth** - Coelacanths are a group of ancient bony fish.
3. **Cichlid** - Cichlids are also a group of bony fish, belonging to the actinopterygii.
Based on evolutionary relationships:
- Frogs (amphibians) are more distantly related to both cichlids and coelacanths, as they belong to a different class (Amphibia).
- Cichlids and coelacanths are both bony fish, and they are more closely related to each other than to frogs.
Therefore, the two species that are likely grouped together on a phylogenetic tree are **cichlid and coelacanth (c)**.
