<span>C. Youthful
"Child-like" as a word can best be replaced by the adjective youthful. It is the correct part of speech to fit into the rest of the sentence, and it means basically the same thing. Acting like a child is acting as one did in youth, so youthful and child-like are very close synonyms. </span>
