Final answer:
It is true that William of Orange was married to James II's daughter, Mary, and was in line for the English throne. They ruled jointly after James II was deposed in the Glorious Revolution.
Step-by-step explanation:
The statement that William of Orange was married to James II's daughter, Mary, and also was in line for the throne of England is true. William of Orange married Mary Stuart, who was the Protestant daughter of the Catholic King James II of England.
When James II was deposed during the Glorious Revolution of 1688, William and Mary were offered the throne by Parliament. They ruled jointly as William III and Mary II. This was a unique situation where a husband and wife ruled together, and their reign had a considerable impact on the political landscape of England, contributing to the evolution of constitutional monarchy.
