Which items are classified as "safety items" checked during each inspection?

The classification of items checked during inspections as "safety items" is focused on those components that directly impact the safe operation of a vehicle. Seat belts, rear view mirrors, and the horn are all fundamental to ensuring that both the driver and passengers are protected while on the road.

Seat belts are essential safety features designed to secure occupants in their seats, reducing the risk of injury during a crash. Rear view mirrors allow for adequate visibility of the road and surrounding traffic, which is crucial for safe maneuvers such as lane changes and merges. The horn serves as an important communication tool between drivers, helping to alert others of potential hazards and ensuring that safety remains a priority in various driving situations.

In contrast, the other options involve components that might contribute to the overall performance or comfort of the vehicle but do not primarily focus on immediate safety concerns. For instance, while air conditioning and headlights contribute to comfort and visibility, respectively, they are not as directly linked to safety as the items listed in the correct option. Similarly, components like the battery and spark plugs relate more to engine performance rather than direct safety, and tires and brakes, though critical for safe operation, are not included in the selected response. Thus, the items classified in the correct answer are
