A Correct answer
Explanation

MSUM is an OLAP (Online Analytical Processing) function used in data warehousing for calculating moving sums across dimensions. While SUM and AVG are standard SQL aggregate functions, they are not specifically OLAP functions. OLAP functions operate across data cubes and dimensions for analytical processing, not simple row aggregation.
