B) A total solar eclipse always occurs when Earth is at perihelion; it is moving fastest at that time.
C) Both Earth and the Moon move clockwise in their orbits, as seen from the north. Thus, during a solar eclipse Earth and the Moon are moving in opposite directions, and during a lunar eclipse they are moving in the same direction.
