Answer:
Option B) Alloy does not oxidise readily at high temperature
Explanation:
Alloys are used in electrical heating devices rather than pure metals because the resistivity of an alloy is more than the resistivity of a pure metal. Moreover alloy does not burn (or oxidize) easily even at higher temperature.
