Final answer:
William of Orange was married to James II's daughter, Mary, and was in line for the English throne, which they jointly ascended after the Glorious Revolution of 1688. The Given statement is true.
Step-by-step explanation:
The statement that William of Orange was in line for the throne of England because he was married to James II's daughter, Mary, is true. William of Orange, a Dutch prince, married Mary, who was James II's Protestant daughter. This marriage was significant as it aligned William closely with the English crown.
Indeed, when James II, who was a Catholic king, was deposed during the Glorious Revolution of 1688, William and Mary were invited to take the throne as joint monarchs in what was seen as a 'bloodless revolution' to preserve a Protestant monarchy. This event is a key moment in British history and is often referred to as the Glorious Revolution or the Revolution of 1688. The Given statement is true.
