What is the role of financial centers in the global economy?  

Financial centers play a critical role in the global economy by facilitating the efficient allocation of capital and resources. Financial centers provide a platform for businesses to access capital and investment, which in turn drives economic growth and development. They also serve as a hub for financial innovation, driving new products and services that improve financial efficiency and promote economic development. While financial centers may provide a safe haven for investors during economic downturns, this is not their primary role. Similarly, while financial regulation and oversight is an important function of financial centers, it is not their primary role in the global economy. Therefore, option B is correct.
