To determine the correct answer, we will go through each option and compare it with the definition given in the question. Option A: Semantic Network. A semantic network is a structure that represents concepts and their relationship with each other. It does involve organizing knowledge, but it's more focused on the relationships rather than an organized cluster of knowledge about a specific object or event. Option B: Conceptual Hierarchy. A conceptual hierarchy is a way of organizing concepts into hierarchical structures, but it mainly focuses on the categorization of topics in an organized manner, and not specifically on a cluster of knowledge about a particular object or event. Option C: Schema. A schema is a cognitive framework or blueprint that helps organize and interpret information. It is an organized cluster of knowledge about a particular object or event, and this definition is what we are asked to identify in the question. Option D: Retrieval Cue. A retrieval cue is a clue or hint that helps to trigger the memory of a specific piece of information. It is not an organized cluster of knowledge, but rather a prompt to aid in recalling information.

After analyzing each option, the term that best fits the provided definition is "schema." Therefore, the correct answer is: C. schema.
