Final answer:
The tradition of troubadours and trouvères, medieval poet-musicians, developed in France, particularly beginning in the Occitan-speaking region with the court of Aquitaine.
Correct option is B France
Step-by-step explanation:
The tradition of troubadours and trouvères developed in France. These poet-musicians of the medieval period were known for their role in crafting and performing lyrical poetry, focusing on themes of chivalry and courtly love during the High Middle Ages. The culture of the troubadours, originating in the Occitan-speaking regions of France, especially the court of Aquitaine, and the trouvères, who were active in the northern regions where the langue d'oïl (Old French) was spoken, gave rise to a rich body of literature and music that influenced many parts of Europe.
An example of the troubadours' impact is depicted by a casket from the court of Aquitaine, housed at The British Museum, which dates back to around 1180 and features troubadours.
