Question

Below are given alternatives to the underlined part, which may improve the sentence. Choose the correct alternative. In case no improvement is needed, choose option D:
Each one of the students in Ms. Smith's art class must bring their own paint brushes, paints and paper.

• A. his or her own
• B. his own
• C. to each their own
• D. no change

Answer 1

Answer: (A)

his or her own

The subject "each one of the students" implies that the subject is singular "each one". 'Each' refers to an individual from a group of students.. Hence the pronoun that follows will also be singular.
The underlined phrase is hence, incorrect. So, D is wrong.
Option A: Since the gender of 'each' is not specified, 'his or her own' is the correct form that replaces the phrase. Hence A is correct.
Option B: It isn't mentioned that the gender of the subject is masculine, hence 'his own' is incorrect here.
Option C states an idiom. It does not refer to the subject here. Hence C is incorrect.
