If you don't mind being bash-specific, then:
shopt -s extglob # this can go in your .bashrc if you like
rm -rf /path/to/!(B)
You can put multiple patterns inside "!(...)", separated by "|". See the
"Pattern Matching" subsection in the bash(1) man page.
If you want something that works in any POSIX shell, you could also use
find, as follows:
find /path/to -maxdepth 1 -name B -o -type d -print0 | xargs -0 rm -rf
You can add extra patterns by adding more "-name whatever -o" fragments
after the first one above.
With both of these, I advise using 'echo' at first in place of 'rm -rf',
just to be sure.
