Answer to Question 1

A

Answer to Question 2

All orbit in almost circular orbits of low eccentricity, close to the ecliptic plane and in the Sun's equatorial plane, and all revolve counterclockwise around the Sun; most also rotate counterclockwise as well, and most moons orbit their planets in the same counterclockwise directions the original solar nebula had.
