Linus Claims That the Added Gravitational Force of Neutrons Holds

Linus claims that the added gravitational force of neutrons holds the particles in a nucleus together.Linnea says that they stick together because they lose their electric charge when they form a nucleus.Which one,if either,is correct,and why?

A) Linus,because more particles exert gravitational forces on one another than exert electromagnetic forces.
B) Linus,because the numerical magnitude of G/k_e is 7.42 *10 ^{- 21}.
C) Linnea,because the numerical magnitude of G/k_e is 7.42 *10 ^{- 21}.
D) Both,because electric charge is lost and then gravity holds the nucleus together.
E) Neither,because gravity is not lost,and the numerical magnitude of k_e/G is 1.35 *10²⁰.
