Solution

The correct option is A Due to high resistivity
An alloy generally has a higher resistivity than its constituent metals. Alloys do not oxidise (burn) readily at high temperatures. For this reason, they are commonly used in electrical heating devices, like electric iron, toasters etc.

So option A is correct.
