The project I'm working on requires a butt joint that will undergo a
little
stress. I'm obviously going the glue the length of the joint, but I'd like
to reinforce it with a)screws, b)dowels, or c)biscuits. Anyone have an
opinion as to which of these 3 would add the most strength to the joint?

Of the 3 choices, B.

If you go to a little more trouble you could do lap joints and strengthen
the joint considerably.
