Question

Choose the option that best corrects the underlined word.

Aircraft passengers must keep seatbelts fastened while the seatbelt sign is on as long as you are in the air.

• A. they
• B. it
• C. them
• D. NO CHANGE

Answer 1

The correct option is A they

Since the reference is to a group of people in third person, third person plural form of the pronoun must be used. Also, since the passengers are the subject, subjective form of the pronoun must be used which is "they". Hence, Option D is correct. The rest of the options do not adhere to this rule, hence incorrect.
