What is the definition of an auto cycle?

An auto cycle is specifically defined as a three-wheeled vehicle that is designed to be steered using a steering wheel, much like a car. This type of vehicle typically combines elements of both motorcycles and automobiles, offering the open design of a motorcycle while providing the structure and driving controls of a car.

The option that correctly identifies an auto cycle highlights its distinctive feature of having three wheels and a steering mechanism, which differentiates it from other types of vehicles. While options reflecting two wheels or four wheels with different styles may highlight other vehicle types, they do not encapsulate the unique characteristics that define an auto cycle. Additionally, the broad categorization of any motorized vehicle fails to capture the specific requirements concerning the number of wheels and steering method that pertain to auto cycles. Thus, option B accurately describes the defining features of an auto cycle.
