Final answer:
The matrix structure is the one that best balances geographical, product, and functional considerations to effectively implement corporate objectives, as it merges two or more structures to capitalize on specialization and respond to specific business needs.
Step-by-step explanation:
The matrix structure is considered to achieve the best balance of geographic, product, and functional considerations required to implement corporate objectives effectively. This organizational structure allows for two or more types of structures to be combined, resulting in a grid-like structure where employees report to both a functional manager and a product or project manager. The matrix structure aims to take advantage of specialization by maintaining functional departments while also being responsive to product development, regional requirements, and project-focused tasks.
