Answer:
c. neither adverb nor adjective
Explanation:
this is not an adverb because adverbs are words that modify a verb and Jesus of Nazareth is not a verb.
this also is not an adjective because an adjective describes the quality or state of being of a noun. Jesus is a noun, he is a person(, place or thing), but other people can't describe something.
