Solution

The correct option is A Invar
The balance wheel of a watch is made of invar. Invar is a nickeliron alloy. It shows very little coefficient of linear expansion. So, the change of its length varies very slightly with change in temperature. Thus time given by this watch is more accurate over a very long range of temperature.
