Fill in the blank with a suitable preposition.
He couldn't find the tickets in his bag. He must have dropped it ________ his way.
The expressions ‘in the way' and 'on the way' are often confused with one another, in spite of their difference. 'In the way' denotes that something/somebody is blocking the route that is to be used, i.e. it indicates an obstruction. Since the given sentence doesn't refer to any obstruction and denotes a route, 'in his way' cannot be used. Hence option A is incorrect. Whereas the expression 'on the way' is used to talk about the route, direction or path used to get somewhere. In the given context, the way can be interpreted as the floor or road that the person uses to get there, therefore ‘on’ is the apt answer. Thus option B is correct. On the other hand, ‘at’ is used to speak about an organization or exact place/spot. Since the sentence doesn’t refer to an exact spot and instead speaks about a route, option C is incorrect. Whereas, ‘under’ means below something, for example, "under the bed". A person cannot drop something ‘under’ his way, therefore, option D is incorrect.
