Adjectives modify nouns and pronouns. Adverbs modify adjectives, verbs, and other adverbs. The adverb seemingly, not the adjective seeming, should be used to modify the adjective unlimited. The idiomatic form to be used here is targeted . .. at rather than targeted ... to. Logic requires that each antibody is meant to deal individually with an invading microbe or foreign substance.

A The adjective seeming should instead be the adverb seemingly.

B The adjective seeming should instead be the adverb seemingly.

C The adjective seeming should instead be the adverb seemingly; the use of all instead of each does not make sense.

D The use of all instead of each does not make sense.

E Correct. This sentence correctly uses seemingly instead of seeming and each instead of all.
