A) The frictional charging process takes place due to the transfer of electrons between the two objects that are rubbed together. When rubbed against each other, some electrons from one body may pass on to the other body. The body that receives the extra electrons, becomes negatively charged.

B)The charging by direct contact process involves the touching of two conductors. It involves the two contacting objects momentarily sharing the net excess charge. The excess charge is simply given a larger area over which to spread in order to reduce the total amount of repulsive forces between them. This process demands that the objects be conductors in order for electrons to move about and redistribute themselves.

C & D) Induction charging is a method used to charge an object without actually touching the object to any other charged object. If we take a positively charged glass rod near small pieces of paper, the rod attracts the uncharged pieces of paper! This is because some of the electrons accumulate at that edge of the paper piece which is closer to the rod.At the farther end of the piece, there is a deficiency of electrons and hence positive charge appears there.such a redistribution of charge in a material, due to the presence of the nearby charged body, is called induction. The rod exerts a larger attraction on the negative charges of the paper piece as compared to the repulsion on the positive charges. This is because the negative charges are closer to the rod. Hence, there is a net attraction between the charged rod and neutral paper pieces.
