Solution

The correct option is C
A copper rod

Except copper, the other three are insulators whereas copper is a conducting object. As soon as it gets charged by rubbing with another material, the electric charge produced on its surface flow through our hand and body into the earth hence it is very difficult to hold charge on copper.
