What is the key difference between diesel high-pressure fuel systems and gasoline port-injection systems?

• A. Diesel uses very high-pressure delivery with direct injection and no spark, while gasoline uses lower pressure with spark ignition and can be port or direct injection.
• B. Diesel uses low-pressure delivery with spark ignition, and gasoline uses high-pressure direct injection.
• C. Diesel uses turbocharging to create pressure, whereas gasoline relies on atmospheric pressure.
• D. Diesel and gasoline use identical fuel pressures and no spark differences.
