Which of the following is a major component of all gas turbine engines?

Explanation:
Air must be captured and delivered smoothly to the compressor in a gas turbine cycle. The inlet duct provides the path for that incoming air, shaping and directing it to the compressor to achieve good flow, reduce losses, and prevent surge. This air‑path component is present in all gas turbine engines, making it a fundamental part of the core operation. Pistons and crankshafts are features of reciprocating engines, not the turbine core, which is why they aren’t universal to all gas turbines. Spark plugs are ignition devices used in some engines, but not a universal, defining component of every gas turbine.
