The correct answer is D. 4213.
The word “stationery” is a noun that refers to writing materials, such as paper, pens, and pencils. The word “bought” is the past tense of the verb “to buy,” which means to acquire something for money. The word “some” is an indefinite article that can be used to refer to an unspecified number or amount of something. The word “he” is a pronoun that refers to a male person.
In the sentence “He bought some stationery,” the word “he” is the subject of the sentence. The word “bought” is the verb of the sentence. The word “some” is an object of the preposition “of.” The word “stationery” is the object of the verb “bought.”
The sentence can be paraphrased as “A male person acquired some writing materials.”
The other options are incorrect because they do not make sense in the context of the sentence. Option A, 1243, is incorrect because the word “stationery” cannot come before the word “bought.” Option B, 4231, is incorrect because the word “bought” cannot come before the word “some.” Option C, 4132, is incorrect because the word “some” cannot come before the word “he.”
