The correct answer is D. 25143.
The word “known” is an adjective that means “famous, well-known, or widely recognized.” The word “he” is a pronoun that refers to a male person. The word “me” is a pronoun that refers to the speaker. The word “to” is a preposition that indicates a direction or destination. The word “is” is a verb that means “to exist or be.”
In the sentence “He is known to me,” the word “known” is an adjective that describes the noun “he.” The word “he” refers to a male person. The word “me” refers to the speaker. The word “to” indicates that the speaker knows the person referred to by the word “he.” The word “is” is a verb that indicates that the speaker knows the person referred to by the word “he.”
The other options are incorrect because they do not make sense in the context of the sentence. Option A, 15423, is incorrect because the word “known” comes before the word “he.” Option B, 25314, is incorrect because the word “me” comes after the word “he.” Option C, 23541, is incorrect because the word “to” comes after the word “me.”
