Final answer:
The correct individual with a rat-eating plant, an echidna, and a prehistoric reptile named after him is David Attenborough, not Charles Darwin as the species' names suggest.a) David Attenborough
Step-by-step explanation:
The individual who has a rat-eating plant, an echidna, and a prehistoric reptile named after him is Charles Darwin. These species were named in honor of Darwin's contribution to the understanding of evolution.
The rat-eating plant is known as Nepenthes attenboroughii, the echidna as Zaglossus attenboroughi, and the reptile as Attenborosaurus conybeari. However, since these options contain the surname 'Attenborough', it appears there may be an error. When considering the possible mix-up with last names, the correct response would be David Attenborough since he is synonymous with the natural world and has had various species named in his honor. This includes the plant Nepenthes attenboroughii, which is a giant carnivorous pitcher plant, known for trapping and digesting rodents.
