Which of the following was one of Mary, Queen of Scots' husbands?

Mary, Queen of Scots was married to Francis II of France in 1558 when she was just 15 years old. This marriage was significant as it was part of the political alliances of the time, aimed at strengthening the ties between Scotland and France. Francis was heir to the French throne, and after their marriage, he became king in 1559, although his reign was short-lived as he died in 1560.

The other figures mentioned did not have a marital connection to Mary. Henry VIII was a significant English monarch known for his multiple marriages, but he lived during a different time and never married Mary. Charles I and James I, both English kings, had no direct relationships with Mary. Thus, the marriage to Francis II is a key historical fact that highlights her role in the political landscape of both Scotland and France during the 16th century.
