A naturally aspirated engine is one that draws air into the combustion chamber solely through atmospheric pressure without any mechanical assistance. In contrast, a turbocharged engine employs a turbine driven by exhaust gases to force more air into the combustion chamber. This process increases the amount of air and fuel that can be combusted, leading to greater power output compared to naturally aspirated engines.

Choosing the correct option highlights that the key difference lies in how air is introduced into the engine. The statement correctly conveys that a naturally aspirated engine relies only on atmospheric pressure for air intake, while a turbocharged engine utilizes a turbine, which compresses air to enhance performance and efficiency. This distinction is crucial in understanding engine performance characteristics and design differences.
