Solution

The correct option is C
It does not corrode easily and can be made into very thin sheets.

The reasons for using gold is that gold will not corrode and can be hammered to a very thin sheet, making the mass very small. This makes it more sensitive to smaller electric charges. Hence it is the ideal material to be used in an electroscope.
