The correct answer is A. Increase trade
Step-by-step explanation:
The Renaissance (15th and 16th century) was a period of emerging ideas and changes in Europe, this period began after the Middle Ages and implied the emergence of humanism as well as artistic and philosophical developments. All of this began in Florence, Italy but soon expanded to all Italy and other countries in Europe such as France.
This occurred because back then Italy was a major commercial center and due to this was visited by people from multiple countries, some of them were even artists, philosophers or similar that learn the new ideas and took them to their own countries. Thus, one of the main factors that helped the Renaissance spread beyond Italy was increased trade.
