The correct answer is: 4123.
The word “excels” is a verb that means to be very good at something. The word “in” is a preposition that indicates a location or position. The word “he” is a pronoun that refers to a male person. The word “painting” is a noun that refers to the act or process of creating pictures with paint.
In this sentence, the word “excels” is the main verb. The word “in” is a prepositional phrase that modifies the verb “excels.” The word “he” is the subject of the sentence. The word “painting” is the object of the preposition “in.”
The sentence can be paraphrased as follows: “He is very good at painting.”
The other options are incorrect because they do not make sense in the context of the sentence. Option A, 1423, is incorrect because the word “he” comes before the word “excels.” Option B, 3241, is incorrect because the word “in” comes after the word “excels.” Option C, 3124, is incorrect because the word “painting” comes after the word “he.”
