Final answer:

Fire hose couplings are typically made of durable, rust-proof materials such as brass, aluminum, and stainless steel. They are designed to withstand high-pressure water flow during fire extinguishing events.

Step-by-step explanation:

Fire hose couplings are typically made of durable, rust-proof materials. These materials are chosen for their ability to withstand the high-pressure water flow that's common during fire extinguishing events. The most commonly used materials in manufacturing fire hose couplings include brass, aluminum and stainless steel. All of these materials are hardy, durable and resistant to rust, making them ideal for use in tough firefighting situations.

So, correct option will be D.
