Which of the following is a component of the combustion chamber?

Explanation:
Ignition inside the combustion chamber requires a dedicated ignition source placed in the chamber to light the fuel-air mixture. The igniter plug serves exactly this role, delivering a spark (or hot surface) to ignite the mixture during start and whenever ignition is commanded. That makes it a component of the combustion chamber. Piston belongs to a reciprocating engine’s cylinder, not a turbine’s combustor; thrust reverser is part of the exhaust system used to redirect thrust, and the start motor is part of the starting system used to spin the engine before ignition, not inside the combustor.
