question about testing in shell programming

[thungmail]

I have 2 different directories. The first has 2 sub-folders A and B. The second as 2 sub-folders C and D and script named "script".There is a code of "script" to list 2 sub-folders C and D

#!/bin/sh
for file in *
do [ -d $file ]  && echo $file
done

I would like to ask how can I make a change if I would like to list 2 sub-folders A and B in the first directory ( using "script" )

find .. -type d
