I would go with "B".

I'm to lazy to do it for you but if you calculate the section modulus
of each joint, you'll find "B" is stronger.

S = M/Z

S = Stress
M = Bending Moment
Z = Section Modulus

Z = I/d

I = Moment of Inertia
d = Distance from centroid to outermost fiber.

I (for a retangle) = bh^3/12 = 1/2ad^2

b = base
h = height
a = area
d = distance from center of area to center of bending moment.

Any decent strength text will give you the formula for a circle.

(Dredged from my memory from all those strength of materials classes
taken so long ago.)

Have fun.
