CMFAS CGI Marine Cargo & Hull Insurance question: master of a vessel deliberately throws part of the cargo overboard to lighten and save

During a storm, the master of a vessel deliberately throws part of the cargo overboard to lighten and save the ship. The owner whose goods were jettisoned is compensated by:

• A A particular average claim against their own cargo insurer alone, with no contribution from other interests
• B A salvage award paid by the destination port authority out of the harbour dues it collects
• C Nothing, because a loss caused deliberately by the master is never recoverable from anyone
• D A general average contribution from all the saved interests, in proportion to their value at risk
