AI Explanation
The correct answer is B) Cycloidal propellers. Cycloidal propellers, also known as Voith-Schneider propellers, are a type of propulsor that does not require a separate rudder for steerage. This is because the cycloidal propeller has blades that can rotate 360 degrees, allowing for precise maneuvering and directional control without the need for a separate rudder. The other options, A) Contra-rotating propellers, C) Conventional fixed-pitch propellers, and D) Tandem propellers, all require the use of a separate rudder for steerage and directional control.
