Which statement captures the metaphorical sense of vehicle?

• A. A means of expressing a certain idea
• B. A device used to transport people around
• C. An object used for carrying cargo
• D. A means or way of expressing a particular idea

Answer: (D)

In metaphorical use, a vehicle is the medium that carries or conveys meaning—the channel through which an idea is expressed. The statement that describes it as “a means or way of expressing a particular idea” fits this sense exactly, naming vehicle as the route through which something is communicated.

The other interpretations focus on literal transport or cargo handling, which are physical senses, not the figurative sense of conveying meaning. One option is very close, but it doesn’t emphasize the expressive channel as clearly as the selected phrasing does.
