Which commercial Boeing aircraft is known for having four engines?

The Boeing 747 is the only aircraft among the listed options that is equipped with four engines. This design is integral to its performance, allowing for a higher passenger capacity and longer range compared to twin-engine models. The Boeing 747, often referred to as a "Jumbo Jet," has been a significant player in long-distance air travel since its debut, offering a unique combination of size and power thanks to its four-engine configuration.

The other aircraft listed are all twin-engine models. The Boeing 737, 757, and 767 are designed for efficiency and lower operating costs, which is why they utilize two engines. This design is suitable for the routes they typically serve, where smaller capacity and range are adequate. The distinction of the Boeing 747 with its four-engine setup sets it apart as a specialized aircraft for carrying large numbers of passengers and cargo over long distances.
