Answer

To determine the correct hierarchy for Homo erectus, we need to understand the taxonomic classification of this species. The hierarchy in biological classification is organized from broad to specific categories. Here’s the step-by-step solution:

1. **Kingdom**: The highest rank in the classification system for Homo erectus is the Kingdom, which is **Animalia**. This includes all animals.

2. **Phylum**: The next level is the Phylum, which for Homo erectus is **Chordata**. This group includes animals with a backbone.

Putting this all together, the correct hierarchy for Homo erectus is:
- Kingdom: Animalia
- Phylum: Chordata
- Class: Mammalia (not listed in options)
- Order: Primata
- Genus: Homo
- Species: erectus

From the provided options, the correct sequence that matches this hierarchy is:
**Erectus, Homo, Primata, Chordata, Animalia**.

Thus, the correct answer is the **first option**.
