Why do the inferior planets go into retrograde only at inferior conjuction?

I believe it has to do because Earth passes up inferior planets while the planets are in inferior conjunction. The only way retrograde works is if the earth is passing a planet. While a inferior planet is in superior conjunction it is not being passed up.

Which positions are the best and worst viewing position for inferior planets and why?

The best viewing position for inferior planets (Mercury and Venus) is when they are at greatest elongation, meaning they are at their farthest distance from the Sun in the sky. This provides the best visibility as they are higher above the horizon. The worst viewing position for inferior planets is when they are at superior conjunction, which means they are on the far side of the Sun and not visible from Earth.
