What are the components of the oxygen system?

The components of the oxygen system include oxygen bottles, oxygen masks, and a distribution system, making the selected answer the most accurate. Oxygen bottles are the containers that store the oxygen under pressure, which is necessary for it to be used effectively, especially in aviation or high-altitude environments. Oxygen masks are the devices that an individual uses to receive the oxygen when needed, ensuring the proper delivery of oxygen to the user's respiratory system.

The distribution system refers to the network of pipes or tubing that connects the oxygen bottles to the masks, allowing for the transportation of oxygen as required. This system is crucial for ensuring that the oxygen is available and can be delivered in the right amounts when needed, particularly in situations where supplemental oxygen is necessary.

In contrast, the other options don't accurately represent the core components of an oxygen system. For instance, mentioning "controls" or "pressurization systems" introduces elements that may be related to the operation of oxygen systems but are not fundamental components of the oxygen delivery system itself. Similarly, referring to "distribution pipes" without explicitly linking them to an oxygen distribution system lacks the specificity required to define the actual components. Therefore, the answer correctly captures the essential elements of the oxygen system.
