💡  A. Functional structure: While a functional structure organizes employees based on specialized functions (e.g., marketing, finance, operations), it may create silos and limit innovation. This structure is more suited to cost leadership rather than differentiation, which requires flexibility and collaboration.  B. Divisional structure: A divisional structure groups activities by product lines, geography, or customer segments. While it allows for some differentiation, it may not foster the high level of cross-functional collaboration needed for continuous innovation and unique offerings.  C. Mechanistic structure: Mechanistic structures are rigid, hierarchical, and heavily centralized. They are best suited for cost-efficiency strategies rather than differentiation, which requires adaptability and creativity.  D. Functional structure with cross-functional teams: This is the best fit for a differentiation strategy because it combines specialization (functional structure) with collaboration and flexibility (cross-functional teams). Cross-functional teams encourage innovation by integrating insights from different departments, helping the organization create unique products or services that stand out in the market.
