Final answer:
The student should choose the option 'needs to bring his or her ticket.'The correct option is A.
Step-by-step explanation:
The accurate choice is A) an individual should present his or her ticket. The sentence contains a word usage error where 'their' is wrongly employed. This is because 'their' is a plural pronoun and does not align with the singular noun 'person'. To ensure consistency in subject-verb agreement, a singular pronoun is required. The appropriate option is to use 'his or her,' a gender-neutral pronoun that concurs with the singular noun 'person.' For instance, in the sentence, "Each person attending the dinner needs to bring his or her ticket to gain entry to the event."
