Final answer:
William the Silent was the key figure leading the Dutch revolt against Spanish rule in the late 16th century, leading to the establishment of the Dutch Republic.
Step-by-step explanation:
The most prominent leader of the Dutch revolt against Spanish rule in the late 16th century was William the Silent (Option A). He played a crucial role in the Eighty Years' War and was instrumental in the establishment of the Dutch Republic. During his leadership, the northern seven provinces of the Spanish Netherlands declared their independence from Spain in 1581, after fighting against Spanish control, which was enforced under King Philip II of Spain, and later his son Philip III. Unlike Peter Stuyvesant, who was more associated with the Dutch administration in New Netherland, or Hugo Grotius, who was an influential jurist and philosopher, William the Silent is most associated with the Dutch revolt and is often considered the father of the Dutch nation.
