What does a typical tune-up for an automobile include?

A typical tune-up for an automobile focuses on the engine's performance and efficiency, which includes essential maintenance tasks that help ensure optimal engine function. Replacing spark plugs is a fundamental part of a tune-up because worn or fouled spark plugs can lead to misfires, reduced fuel efficiency, and increased emissions. Additionally, checking the ignition timing is crucial, as it ensures that the air-fuel mixture is ignited at the right moment in the engine cycle, which is vital for smooth operation and performance.

The other options, while important for vehicle maintenance, do not specifically align with the classic definition of a tune-up. Changing the oil and rotating tires are part of regular maintenance but not specifically associated with a tune-up. Inspecting transmission fluid focuses on the transmission system rather than the engine itself, and reprogramming the engine control module is a more advanced procedure that may not be directly related to the routine maintenance that a tune-up entails. Thus, option B accurately captures the essence of what a standard tune-up involves.
