The bilayer is structured in such a way that it complements the extracellular fluid around the cell as well as the cytoplasm within the cell. This is because the extracellular fluid is hydrophillic, the outside of the membrane protein is hydrophillic, the middle of the membrane protein is hydrophobic, the inside of the cell (the cytoplasm) is hydrophillic and the inside of the membrane protein is hydrophillic.

Answer:
The answer to the question above is option B (Eumetazoa and Lophotrochozoa)
Explanation:
Cycliophorans exhibit sexual dimorphism, they live on the mouthparts of their lobster hosts using anterior buccal funnel; oval-shaped trunk; and posterior, acellular stalk, with an adhesive disc which they use to attach themselves to their hosts’ mouthparts. Cycliophorans do not feed during free swimming stages and are filter feeders during their sessile stage.
Cycliophorans live on lobsters, they do not generally adversely affect their hosts, although it is possible for large numbers of cycliophorans to clog their host's mouthparts.
Coelom is the fluid-filled cavity within the body of most multicellular animals, except some invertebrates, it acts as a cushion for the internal organs of the organism. Animals which have a space between their digestive tract and body wall and entirely lined by mesoderm are termed as coelomate animals.
Eumetazoans include radially-symmetrical animals and bilaterally-symmetrical animals that have true tissues organized into germ layers, and an embryo that goes through a gastrula stage, and are distinguished by their characteristic epithelia,
The characteristic features of the group lophotrochozoa are, they are animals with ciliated larval phase, and they have the presence of a trochophore larvae and a feeding structure called lophophore.
