  In this paper we continue to study Belavin-Drinfeld cohomology introduced in
arXiv:1303.4046 [math.QA] and related to the classification of quantum groups
whose quasi-classical limit is a given simple complex Lie algebra. Here we
compute Belavin-Drinfeld cohomology for all non-skewsymmetric $r$-matrices from
the Belavin-Drinfeld list for simple Lie algebras of type $B$, $C$, and $D$.
