Answer is option "c"
Explanation:
- Frogs have lungs, cockroaches have trachea, while fishes have gills for respiration. Earthworms don't have special organs for respiration, instead, they breathe through their skin. This type of respiration is known as cutaneous respiration. Earthworms lack specialized distinct organs for respiration.
- The respiratory exchange occurs through a moist body surface into their bloodstream. Earthworms need specific unmistakable organs for breath. The respiratory trade happens through a soggy body surface into their circulation system.
- Oxygen diffuses through the worm's body surface and diffuses internal to the system of vessels lying simply under the body surface.
- Hence, the right answer is option c "Earthworm".
