A. all vertebrate embryos have tails.
This statement is correct because during the early stages of development, all vertebrate embryos exhibit a structure commonly referred to as a tail. This tail is a remnant of evolutionary history and is evident in the embryonic development of fish, amphibians, reptiles, birds, and mammals before they may lose or modify it in later stages of development.
The other statements (B, C, and D) are incorrect, as not all vertebrate embryos have hair, legs, or ears at any stage of their development.
