• B. On-Board Diagnostics
• C. Overhead Beam Detection
• D. Oil Basic Data

Answer: (B)

The acronym "OBD" stands for "On-Board Diagnostics." This system is critical in modern vehicles as it monitors various vehicle subsystems to ensure they are operating correctly. The OBD system collects data from engine performance, emissions control systems, and other essential components, which helps identify malfunctions or inefficiencies. It also provides diagnostic trouble codes (DTCs) that technicians can use to troubleshoot problems, making it an essential tool for automotive diagnostics and repair. Utilization of OBD systems has become standard in the automotive industry due to their ability to facilitate routine checks and enhance vehicle reliability and emissions control, thus playing a pivotal role in environmental protection and ensuring vehicles meet regulatory standards.
