Explanation: In the context of Indian geography and transportation, prepositions play a crucial role in accurately describing the relationship between different locations. The preposition "between" is specifically used to indicate a direct connection or route that links two specific points. In this case, the national highway that connects Chennai and Bengaluru is described as being "between" these two cities.
To understand the usage of "between," it is important to recognize that it is used when there are exactly two points or entities involved. For example, a highway that connects two cities would be described as being "between" those cities. This preposition is often used in contexts such as "the road between two towns," "the bridge between two islands," or "the flight between two airports."
In contrast, "among" is used when referring to a group of more than two items or entities. For instance, "the treasure is hidden among the trees" or "the prize will be shared among the winners." The preposition "for" implies a purpose or benefit, such as "the scholarship is for students" or "the book is for children." Lastly, "around" suggests a circular or surrounding relationship, like "the park is around the lake" or "the fence is around the garden."
In the given question, the national highway is a direct connection between Chennai and Bengaluru, making "between" the correct preposition to use. The other options do not accurately describe the relationship between the two cities in the context of a highway connecting them. Therefore, the correct answer is "Between."
Understanding the correct usage of prepositions is essential for clear and accurate communication, especially in contexts involving geographical locations and transportation routes. This knowledge is particularly useful in competitive examinations and general knowledge assessments where precise language is required to convey specific relationships and connections.
