The answer could have been A if placed well (Human and fish) but it wasn't...
The most relatable answer there is C which is Toad and Fish respectively... Toads have 4 or less
U may be wondering that Rat has a taller tail 😅 but actually fish possesses up to 30 or even more Caudal vertebrae than rats with 6-7 Caudal vertebrae...
That is really unreal 💯... Because initially I thought rats should have more than fish
The total number of caudal vertebrae in animals X and Y is 4 and 27 respectively. Based on this information, the animals are likely to be:
C. Toad and fish.
Explanation:
Caudal vertebrae are the bones that make up the tail of an animal. Fish and toads have tails, while rats and humans do not. The number of caudal vertebrae varies widely among different species, but in general, fish have more caudal vertebrae than toads.
Therefore, if animal X has only 4 caudal vertebrae, it is more likely to be a toad than a fish, since toads have shorter tails than fish. If animal Y has 27 caudal vertebrae, it is more likely to be a fish than a toad, since fish have longer tails than toads.
Therefore, the animals are most likely a toad and a fish, which is option C.
