Please see below.

#### Explanation:

The force is directly proportional to the product of charges i.e.

(a) As one of the charges is doubled, their product too is doubled and force is doubled.

(b) if both charges are halved, their product will become one-fourth and force too will become one fourth.

(c) if

(d) if
