C Correct answer
Explanation

An OLAP cube is a logical representation of multidimensional data that enables fast analysis of data across multiple dimensions. While it appears as a multi-dimensional structure to users, the underlying physical storage can be implemented in various ways (relational, specialized formats). The 'logical' term correctly describes this abstraction layer that simplifies complex data navigation.
