Answer:
B). A center of operations.
Step-by-step explanation:
The word 'base' has different denotations and connotations varying on the context in which it is used. In the given context, it stands for 'a central place from where all the decisions are made for a specific purpose or an organization.' Here, the harbor which is 'well protected from the sea' is reachable and therefore, the 'vessel sailed to Dutch West India Company' which will serve as the base(center of operations) from where all the decisions or actions would be controlled. It will serve as the center from where the entire company trade will be operated. Thus, option B is the correct answer.
