Which outcome results when rapid, uncontrolled fuel ignition occurs within each engine cycle?

💡 Explanation

Uncontrolled fuel ignition produces detonation, driving down performance; because much less energy does useful work, the system dissipates energy as waste heat via entropy, overall thermal efficiency decreases; therefore Option A is correct, rather than better fuel economy.
