Some passengers misplaced their luggages before boarding the train.

Correct option is A

The correct substitution of the highlighted words is (a) misplaced their luggage.
Explanation:
The word “luggage” is an uncountable noun and does not have a plural form like “luggages.” Even when referring to bags of multiple people, the correct form remains “luggage.”
Grammatical rule used:
Uncountable nouns do not take a plural ‘s’. Words like luggage, furniture, advice, information are always singular in form.
Example:
Incorrect: He carried two luggages.
Correct: He carried two pieces of luggage.
Information booster:
To make uncountable nouns countable, use phrases like "pieces of," "items of," etc.
E.g., Three pieces of luggage were stolen.
