The basic gas turbine engine is divided into two main sections: the cold section and the hot section. Which option correctly describes this statement?

• A. ,
• B. The hot section handles combustion
• C. The cold section and hot section are the two main parts
• D. There are four main sections

Answer: (B)

In a basic gas turbine, combustion happens in the hot section. The cold section is where air is brought in and compressed, staying relatively cool to protect components, while the hot section houses the combustor where fuel is burned and the resulting high‑energy gases flow to the turbine. Saying that the hot section handles combustion pinpointly describes what that part does within the two-section setup, tying the division to the essential function that defines the hot section. The other ideas either focus on the number of parts or on what happens in the cold section, which doesn’t describe the combustion role as directly.
