Bulb A tied to B(a) Bulb C tied to B(b)

Thanks to all who replied to my question. I didn't realize this would be
so involved. I thought it was just a simple wiring problem.

If there are two bulbs at B, wouldn't two single pole switches do the
job, one for A, B(a), the other B(b), C?



What made a seemingly simple question complicated was that you said you
wanted "B" controlled by two switches.



If you have two bulbs at"B" then a single pole switch indeed could
control A and B(a) and the second single pole switch could control
B(b) and C
