The correct answer is C. 24153.
The word “one” is a pronoun that refers to a person or people in general. The word “elders” refers to people who are older than others. The word “should” is a modal verb that expresses obligation or necessity. The word “obey” means to follow the orders or commands of someone in authority.
In the sentence “One should obey one’s elders,” the word “one” refers to any person, and the word “elders” refers to people who are older than that person. The word “should” expresses the obligation or necessity of obeying one’s elders. The word “obey” means to follow the orders or commands of one’s elders.
The other options are incorrect because they do not make sense in the context of the sentence. Option A, 25314, is incorrect because the word “one” comes before the word “elders.” Option B, 24513, is incorrect because the word “should” comes after the word “elders.” Option D, 54123, is incorrect because the word “obey” comes after the word “should.”
