Solution
The correct option is D electrostatic force Frictional force and muscular force is an "example" of contact force, contact force is not a name of a force in itself.
Electrostatic force is an example of non contact force in which two charged body either attract or repel from eachother, here the example is of a plastic scale and paper pieces which are getting attracted to eachother due to difference in electrostatic charges.
