In flameout scenarios, which component is primarily responsible for re-ignition?

Explanation:
When flameout occurs, re-ignition depends on the ignition system. The igniters, energized by the exciter, provide the high-energy spark (or sparks) needed to ignite the fuel‑air mixture in the combustor. This ignition source is what restarts combustion once fuel flow is established and the air is at the right temperature and pressure for ignition. Other systems play supporting roles but do not initiate ignition: the fuel pump ensures fuel is available at the right pressure, the turbocharger supplies the air needed for combustion, and the oil system only provides lubrication and cooling. So, the ignition system is the component responsible for re-ignition.
