What key information does the World Bank - Doing Business website provide?

The World Bank - Doing Business website is designed to provide comprehensive data on the regulatory environment for businesses in various countries, focusing specifically on the ease of doing business. It offers insights into business regulations that local firms face, which includes information on starting a business, dealing with construction permits, getting electricity, and registering property, among other things. This data helps businesses and policymakers understand the regulatory landscape and identify areas for reform to improve the business environment.

While the other options touch on important aspects of global business, they don't capture the primary focus of the Doing Business site. The site is not dedicated to providing a historical review of global trade agreements, specific import/export regulatory burdens, or taxation laws by country, even though these topics are significant in international business considerations. Instead, its primary emphasis is on the regulatory environment affecting local enterprises directly, making the understanding of option B pertinent and accurate.
