A) Parasites are lower organisms, and this is why they have simple morphologies.

Simple morphologies have been naturally selected for in most parasites because complex morphologies require more energy and resources to maintain, which are often limited in parasitic environments. Additionally, complex morphologies may make it difficult for parasites to navigate and attach to their hosts. Thus, natural selection has favored simpler morphologies in parasitic species.
