C.

Reason: since all mammals  are warm blooded as stated, specie a will definitely  be warm blooded as a mammal too.

Hanoch is rich because he doesn't pay taxes and he doesn't pay taxes because he is rich

- this implies that the relationship works backwards and forwards (no taxes => rich | rich => no taxes), but we know rich people are supposed to pay taxes, so this relationship isn't quite accurate

All mammals have a backbone and species A has a backbone, so it must be a mammal

- mammals are a subset of animals with backbones, so there are animals that have backbones that aren't mammals; the species could be outside the mammal subset and still have a backbone

All mammals are warm blooded and species A is a mammal so species A is warm blooded

- mammals are a subset of warmblooded animals, so if species A fits within mammals, it fits within warm blooded animals, too

Peter said an election will be called this spring, but he is a liar so there will be no election

- Peter's honesty and an election are not related events; if he's lying, the election could be in summer, winter, or fall still
