Why Toad in Phylum Chordata Give me Reason?

Toads belong to Phylum Chordata because they possess the key characteristics that define this group, including a notochord, a dorsal nerve cord, and pharyngeal slits at some stage of their life cycle. Specifically, toads are amphibians, which are a subphylum of Chordata, and they exhibit these features during their development. Additionally, they have a backbone, which is a characteristic of vertebrates within Chordata. This classification reflects their evolutionary relationships with other chordates, including fish, reptiles, birds, and mammals.
