Answer:
The correct answer is D. In Holland, a steward known as the stadtholder assisted the government. This office was held by the prime minister of the republic.
Step-by-step explanation:
Stadtholder was the title of one of the most important officials in the Dutch Republic. Originally, the stadholder was a nobleman who exercised authority on his behalf in the landlord in one or more regions. At first this happened only exceptionally, but the Burgundian House acquired more and more territory in the fifteenth century and because of its extensiveness needed permanent deputies. Stadtholders sat on the Council of State, were able to convene the regional states and chaired the court.
