Uranium-238 is less stable than oxygen-16. What accounts for this difference?

(A) Uranium is a solid, while oxygen is a gas.
(B) Unlike oxygen-16, uranium-238 has a nucleus in which repulsive electric forces surpass the strong nuclear forces.
(C) Oxygen-16 has fewer electrons than uranium-238.
(D) Uranium-238 has fewer neutrons than oxygen-16.
(E) Unlike uranium-238, oxygen-16 has a nucleus in which the strong nuclear forces are overcome by repulsive electric forces.


Please and thank you!
