 Fill in the blank(s) with correct word

Question 2

Why does the electric force dominate at the atomic scale while the gravitational force dominates on the large scale that includes the solar system and beyond?
 a. Atoms have no net charge, making electrical forces within atoms negligible.
  b. There is no gravitational force within atoms, because the law of gravitation applies only to large objects.
  c. Atomic particles have too little mass for gravitational attraction to compete with electric forces.
  d. At large distances, individual charges have essentially no effect since, overall, atoms are electrically neutral.
  e. Both c. and d.
