The correct answer is:

(b) False

Total friction is not negligible compared to rolling friction. While rolling friction is lower than sliding friction, total friction includes multiple factors such as rolling, sliding, and other resistive forces within the engine. Therefore, total friction is generally greater than rolling friction alone.
