Final answer:
Visual Business Director can be used to inspect interactions of a single customer, compare two datasets, and predict customer behavior. It has deep analytical and simulation features to understand customer journeys and behaviors.
Step-by-step explanation:
Visual Business Director (VBD) is a component within certain business analytics and decision management software platforms which can be used to perform a variety of tasks. Option A, inspecting interactions of a single customer, is a plausible use of VBD, as it allows users to dive deep into individual customer journeys. Option B, comparing two datasets, is also a possible use for VBD because it has analytical capabilities that can allow for such comparative analysis. Along with these, option C, predicting customer behavior, is another function that might be executed with the help of advanced analytics and simulation features within VBD. However, regarding option D, importing and inspecting an external dataset, while many business intelligence tools do offer functionalities to import and analyze external datasets, this is not the primary or exclusive use for VBD, and it's usually a feature of the broader analytics platform in which VBD is a component.
