B) halved.
C) unchanged.
D) doubled.
E) quadrupled.

According to Coulomb's Law, the electric force is proportional to the product of the charges and inversely proportional to the square of the distance between them. Doubling both the charges increases the force by a factor of four, while doubling the distance decreases the force by a factor of four, resulting in no net change in the force.
