Who was the king of the Franks and Holy Roman Emperor?

• A. Becket
• B. Saint Benedict
• C. Magna Carta
• D. Charlemagne

Answer: (D)

Charlemagne is the figure described here. He ruled as king of the Franks and then, in a landmark moment in 800, was crowned Holy Roman Emperor by the pope. This coronation unified a vast Western European realm under a single ruler and created the political and symbolic foundation of the Holy Roman Empire for centuries to come. Charlemagne’s reign also spurred the Carolingian Renaissance, strengthening administration and learning across his empire.

Other options don’t fit because they aren’t rulers who held both titles: Becket was an English archbishop in the 12th century, not a Frankish king or emperor; Saint Benedict was a monk and founder of a monastery; Magna Carta is a 13th‑century English charter, not an individual.
