Option B

waste spark ignition system

Explanation:

The waste spark ignition system has two spark plugs connected to the ends of one coil therefore they share the same coil. coil-on plug ignition system is the most common system that modern vehicles use while distributor ignition system mainly triggers the firing of the ignition coil, to control timing advance, and to route or distribute the coil's high voltage output to the individual spark plugs.
