    B

    Their activity is highly concentrated in the hippocampus

    C

    D

    Why? Semantic and episodic memories are both subcategories of declarative memory, which is the memory of facts and events that can be consciously recalled or declared. While semantic memory (focused on facts, concepts, and knowledge about the external world) mainly activates the frontal and temporal cortexes, episodic memory (our memory of experiences) activity is initially concentrated in the hippocampus, and then stored in the neocortex.
