What Makes Gravity the Main Force Determining the Large-Scale Structure

What makes gravity the main force determining the large-scale structure of the universe?

A) Gravity is the strongest of the four fundamental forces.
B) Gravity is the only force that has an infinite range.
C) While the electromagnetic force of a charged particle has an infinite range, it is usually screened (and limited) by the existence of charges of the opposite sign. Ordinary matter has only one sign and therefore does not screen other gravitational forces.
D) The gravitational force, while short-ranged, is the only force that affects all particles: photons, quarks, changed particles, uncharged particles.
