Blood does not transport oxygen in

Solution
The correct option is A Cockroach
- Blood of cockroaches and beetles (both belong to class Insecta) is hemolymph, a clear fluid that does not have any oxygen-carrying pigment (hemoglobin) and hence does not serve in oxygen transport.
- It serves in the transport of nutrients and waste products.
- Spiracles are the small openings present along the edges of the abdomen of insects, through which respiratory gasses are carried to and from tissues via small tubes called tracheae.
- Earthworms, frogs, cats, and humans have red-colored blood rich in hemoglobin protein that serves as an oxygen carrier.
