With awk:
awk -F, 'NR==FNR dup[$2, $3, $4]++; next (dup[$2, $3, $4]==1)' infile infile
Here, we are processing input infile two times, first read the file and saving each duplicated lines according to the specified fields $2, $3 and $4 into the associated array named dup; the ++ is incrementing those lines occurrences every time.
At next process, checking and will print the entire line if the specified fields occurred only once.

For example:
egrep '^[^,]*,11,12,B,' input.file
Explain:
^ from begining of the line
[^,] anything what is not the ','
* as many times as possible
,11,12,B, that what you search for
