Depends on what your goals are.  What do you want to achieve using BGP on
these routers?  Do you want the Branch A router to learn all the routes
from Branch B and HQ and do path selection on its own?  Should Branch B
simply default route to Branch B and HQ and let those routers make the
outbound transit decision?  Do you want to prefer one exit path vs another?
...etc...etc...
