Answer: (C)

Verified step by step guidance

1. Begin by understanding the context of the phrase 'use it or lose it' in relation to memory and forgetting.
2. Recognize that this phrase suggests that if information is not actively used or rehearsed, it may be forgotten over time.
3. Identify the theory of forgetting that aligns with this concept. The 'decay theory' posits that memory traces fade over time if they are not accessed or used.
4. Contrast this with other theories of forgetting: proactive interference (where old information interferes with new information), retroactive interference (where new information interferes with old information), and encoding failure (where information is never properly stored in memory).
5. Conclude that the 'decay theory' is the most appropriate explanation for the 'use it or lose it' concept, as it emphasizes the natural fading of unused memories over time.
