Which of the following components are included in the four major systems of a rocket?

The four major systems of a rocket are correctly identified as including control, propulsion, structure, and payload. Each of these systems plays a crucial role in the overall functionality and performance of the rocket.

The control system is essential for the stability and maneuverability of the rocket during flight. It encompasses the mechanisms that help adjust the rocket's orientation and trajectory.

The propulsion system provides the necessary thrust to lift the rocket off the ground and propel it through space. This system includes engines or motors and the fuel required for combustion.

The structure system refers to the physical framework of the rocket, which must be both lightweight and strong enough to withstand the forces experienced during launch and flight.

Lastly, the payload system pertains to the cargo or mission-specific instruments that the rocket carries, whether they are satellites, scientific instruments, or crewed spacecraft.

Other options do not align with the standard classification of rocket systems. For instance, options mentioning guidance, navigation, communication, or components like thrusters and wings do not accurately represent the fundamental systems typically categorized in rocketry. These elements may be part of the overall operational context or specific applications but do not constitute the four major systems foundational to rocket design and function.
