Answer A, There is a little trick in the question"What destination versions are supported for a Multi-Version Cluster Upgrade? " The R77.30 there isn't destination version

The Multi-Version ClusterClosed (MVC) in an R81 Cluster MemberClosed supports synchronization with peer Cluster Members that run one of these versions: R80.10 (or higher)* R77.30 In a Multi-Version Cluster, the Cluster Members can run only these versions: R81 and R80.10 (or higher)* R81 and R77.30

See https://sc1.checkpoint.com/documents/R81/WebAdminGuides/EN/CP_R81_Installation_and_Upgrade_Guide/Topics-IUG/MVC-Upgrade-Supported-Versions.htm? which suggests R77.30 is supported. But the question is what DESTINATION version is supported.

It´s talking about destination not source or supported version.

Its asking destination, no source version. Answer is A
