Explanations:In the context of travel and transportation, prepositions play a crucial role in describing the route taken from one place to another. The sentence "The oriental express is a Hyderabad-bound train from Delhi and it goes _____ Bhopal" requires a preposition that accurately conveys the train's route, specifically indicating that Bhopal is a stopover or a point on the route to Hyderabad.
The correct preposition to use in this context is "via." "Via" is commonly used in travel contexts to indicate that a journey passes through a particular place on the way to the destination. It is often used in the context of transportation routes, such as train or bus routes, to specify intermediate stops or points of passage. For example, "The train goes via Bhopal" means that the train passes through Bhopal on its way to Hyderabad.
Other prepositions like "through," "by," and "across" have different meanings and are not appropriate in this context. "Through" suggests passing through a place but does not necessarily imply a stopover or a specific route. It is more appropriate for describing movement within a place rather than a route to a destination. "By" typically indicates the means of transportation, such as "by train," rather than the route taken. "Across" implies crossing over a place, often a broader geographical area like a country or a region, and does not convey the idea of passing through a specific stopover on a train route.
Therefore, "via" is the most appropriate preposition to use in this sentence, as it clearly conveys that the train passes through Bhopal on its way to Hyderabad.
