To achieve a truly multicultural organizational culture, management should prioritize actions that promote equal representation, integration, and inclusion, moving away from monolithic practices.

To achieve a truly multicultural organizational culture, management should prioritize actions that promote equal representation, integration, and inclusion, moving away from monolithic practices.

Let's evaluate each statement:

• A. Adopt policies reflecting Employment Equity requirements: Employment Equity policies are designed to ensure fair representation and opportunities for all groups, directly supporting the goal of equal representation and inclusion in a multicultural organization. This is a priority.
• B. Expect minority employees to adapt to the dominant culture: This approach is characteristic of a monolithic or assimilationist culture, not a multicultural one. A multicultural organization values and integrates diverse perspectives, rather than expecting one group to conform. This is not a priority.
• C. Blend sub-cultures at all organisational levels: "Blending" sub-cultures can be interpreted as actively integrating and synthesizing different cultural elements to create a richer, more inclusive organizational culture, rather than simply tolerating differences or expecting assimilation. This contributes to integration and inclusion. This is a priority.
• D. Maintain strict monolithic practices: A monolithic organization is the opposite of a multicultural one. Maintaining such practices would directly contradict the goal of transformation. This is not a priority.
• E. Encourage interaction between diverse employee groups: Promoting interaction helps foster understanding, reduce stereotypes, and build cohesion among different groups, which is essential for integration and inclusion in a multicultural environment. This is a priority.

Based on this analysis, statements A, C, and E are the actions management should prioritize.

The final answer is $\boxed{\text{C. Statements A, C, E}}$
