The correct answer among the choices given is option B. The length of the metal threads at the end of a spark plug is called the insulator. The insulator is the main part of a spark plug and is typically made from alumina. This is a very hard ceramic material with high dielectric strength.
At the 'b' point, partway through the rise in voltage, the spark plug reaches the discharge voltage and a spark is generated between the electrodes. Between 'b' and 'c' is called the capacitance spark. At the start of the discharge, the spark is generated by the electrical energy stored in the secondary circuit.
