Final answer:
The statement is true. William of Orange became William III of England, ruling jointly with his wife Mary II after James II's deposition.
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, also known as William III of England, and his wife, Mary II, were offered the throne by the English Parliament after James II was deposed during the Glorious Revolution of 1688. Their joint reign marked the beginning of a constitutional monarchy, which balanced the powers between the monarchy and Parliament. This joint reign marked a significant shift in England's governance, laying the groundwork for a balanced power structure, elevating the influence of parliamentary governance, and shaping the trajectory of constitutional principles within the monarchy.
