[AI-generated answer — Explain Bot]

The correct answer is vertebrates. Vertebrates are animals that have a backbone or spine. To arrive at this answer, we can use deductive reasoning based on the given options. First, we know that animals with backbones are being referred to. Looking at the options, "simple," "complex," "invertebrates," and "strong" do not directly refer to animals with backbones. However, the option "vertebrates" does explicitly mention animals with backbones, making it the correct answer. Therefore, the animals having backbones are called vertebrates.
