The correct answer is D. 21354.
The first word is “a”. This is an indefinite article, which means that it does not refer to a specific person or thing. The second word is “many”. This is an adjective that means “a large number of”. The third word is “man”. This is a noun that refers to an adult male human. The fourth word is “injured”. This is an adjective that means “having been hurt or damaged”. The fifth word is “was”. This is a verb that means “to exist or live”.
The correct order of the words is 21354. This is because the first word is an indefinite article, which means that it does not refer to a specific person or thing. The second word is an adjective that describes the first word. The third word is a noun that is the subject of the sentence. The fourth word is an adjective that describes the third word. The fifth word is a verb that completes the sentence.
The other options are incorrect because they do not follow the rules of grammar. Option A, 21453, is incorrect because the adjective “many” comes before the noun “man”. Option B, 23514, is incorrect because the verb “was” comes before the adjective “injured”. Option C, 24153, is incorrect because the adjective “injured” comes before the noun “man”.
