Correct answer only !

grounding allows charged objects to become neutral by electrons either flowing from the earth to the object or electrons flowing from the object to the earth through a conductor.

TRUE

Explanation:

Grounding of an object means we connect the given object to the earth by a conducting wire.

here we know that Earth is considered as a large conductor with ZERO potential which means if we connect an object to the earth then it will come to zero potential.

Now if an object is initially charge and then it is connected to Earth for grounding then in that case the final potential of the object must be zero.

In order to make the final potential to be zero we need to transfer all its charge to the earth so in order to make it neutral either electrons are flowing into the object or it will flow out of the object.

so here this is a TRUE statement
