Show answer & explanation
Correct answer: B
Explanation
Correct Answer
on
Explanation
The sentence requires a suitable preposition to complete the expression regarding holiday plans. In standard English grammar, the noun vacation always takes the fixed preposition on when describing the state of being away for a holiday.
While many people mistakenly use "for" or "in" due to direct translation from their native languages, phrases like "go on a vacation," "go on a trip," or "go on a journey" are established collocations that do not change.
The other choices do not work because "at" is used for specific points or locations, "in" is used for enclosed spaces or periods of time, and "for" would only be used if the structure was changed entirely, such as "leaving for a week." Therefore, on is the only grammatically correct option.
Key Points
The fixed expression go on is always paired with travel or holiday nouns like vacation, trip, cruise, safari, or tour.
The incorrect phrase go for is a common trap in competitive exams and should be avoided when dealing with the word vacation.
