Final answer:
A limitation associated with a decentralized organizational structure for advertising is that brand managers often compete for management attention, marketing budgets, and other resources, as described in option D.
Step-by-step explanation:
The question is asking which of the following describes a limitation associated with a decentralized organizational structure for advertising. Among the options given, brand managers often end up competing for management attention, marketing budgets, and other resources is a limitation that is commonly associated with decentralized structures.
In a decentralized organizational structure, multiple managers or teams may have their own budgets and decision-making authority within the overall organization. This can lead to conflicts as brand managers vie for a limited pool of resources and management support. Large advertising budgets and established brand names, like those of Coca-Cola or Pepsi, can further contribute to competition within the organization, as managers work to match the success of these well-known brands.
Thus, option D correctly describes the limitation: Brand managers often end up competing for management attention, marketing budgets, and other resources in a decentralized organizational structure.
