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.
A spark plug is said to be hot if it is a better heat insulator, keeping more heat in the tip of the spark plug. A spark plug is said to be cold if it can conduct more heat out of the spark plug tip and lower the tip's temperature. Whether a spark plug is hot or cold is known as the heat range of the spark plug.
