Physics Question: Static Equilibrium?

The question is on this picture

http://edugen.wiley.com/edugen/courses/crs4957/hal...

The practice question was: "The figure gives six overhead views of a uniform rod on which two or more forces act perpendicularly to the rod. If the magnitudes of the forces are adjusted properly (but kept nonzero), in which situations can the rod be in static equilibrium?"

The answers are 'c', 'e', and 'f'.

I can't even begin to figure out why...

Why are these answers, the answers?

Thank you so much in advance!

    This is because a, b and d are having net clockwise, anti clockwise and anti clockwise moments respectively.

    Whereas c, e and f are having both clockwise and anti clockwise in each of them and thus static equilibrium are possible in them ---answer
