B Correct answer
Explanation

Earthworms don't actually have hearts in the way vertebrates do. Instead, they have five aortic arches that pump blood through their circulatory system. While these function similarly to hearts by pumping blood, they are structurally different from true hearts and are more accurately described as pulsating vessels rather than actual hearts.
