At what time and from what source did the majority of the craters on the Moon form?

(a)   During less than the first billion years of the Moon=s life, from debris left over from the formation of the solar system.
(b)   Increasing to a maximum impact rate 2.5 billion years ago as collisions between asteroids produced more and more debris fragments, then dropping off as large asteroids became rare.
(c)   More-or-less uniformly over the life of the Moon due to a roughly constant supply of rocky and icy debris from the outer solar system.
