B. "that he could not find the specific salt needed to make his transformation."
The correct answer is "it explains that he could not find the specific salt needed to make his transformation". In the novel "The Strange Case of Dr Jekyll and Mr Hyde", Dr Jekyll transforms into Mr Hyde by a chemical solution that he made by mixing different ingredients, one of them being a mysterious salt. Dr Jekyll could not find the specific salt, so he was forced to confess his crimes hoping to find it.
