Which three components make up the front end sheet metal of an automobile?

The front end sheet metal of an automobile consists of critical components that not only contribute to the vehicle's aesthetics but also play a functional role in protecting the engine and enhancing aerodynamics. The grille, hood, and fenders are the primary elements that make up this structure.

The grille is the front-facing component that allows air to flow into the engine compartment for cooling while also serving as a distinctive styling element for the vehicle. The hood covers the engine bay, protecting it from external elements and providing access to the engine for maintenance. Fenders, located on either side of the vehicle, protect the wheels and the vehicle's body from debris and mud, while also contributing to the overall appearance of the vehicle's design.

The other options, while they list various components found on or near the front of a vehicle, do not accurately represent the three primary metal components that directly constitute the sheet metal structure at the front end of an automobile.
