Step-by-step explanation:
A charge is a scalar quantity associated with every material. when we say a body or an object is charged then it means that a body or an object gained a positive charge or negative charge.
A conductor is a metal that contains a lot of electrons in it.
A dark knob or a ground is the source or sink where any charge is dumped.
(1)
when there is a negative charge on an object that will be spread over the surface by the Coulomb force.
so (c) spread out over a large area on the object.
(2)
both the positive and negative charges move to the conductor and exit the conductor.
(3)
(b) a person can not be shocked if they have a neutral charge.
All options have been defined.
