  2. The no of dimensions is usually restricted to 10 or less

  3. Scalability is good

  4. It has a good user interface and functionality

C Correct answer
Explanation

MOLAP (Multidimensional OLAP) uses pre-computed cubes for fast query performance. However, scalability is POOR, not good. MOLAP struggles with large datasets because cubes require extensive pre-computation and storage. Processing overhead for large datasets is high because all aggregations must be pre-calculated. Dimensions are often restricted (commonly to 10 or fewer) due to cube explosion. User interface is good because pre-computed results enable instant responses. Option C is actually NOT true about MOLAP - it's the limitation.
