Explanation:

A. Adjective: An adjective modifies a noun or pronoun. In this sentence, 'like' is not modifying any other word.\nB. Noun: In the sentence "We shall not see his like again," 'like' functions as a noun, meaning 'someone or something similar to him' or 'his equal'. The possessive pronoun 'his' modifies 'like', which is characteristic of a noun phrase.\nC. Adverb: An adverb modifies a verb, an adjective, or another adverb. 'Like' is not functioning as an adverb here (e.g., 'He runs like a deer,' where 'like' is a preposition).\nD. Verb: A verb expresses an action or a state of being. 'Like' is not acting as a verb in this sentence (e.g., 'I like ice cream').
