Step-by-step explanation:
A significant event that took place in England in 1346 was A.
The Battle of Crécy.
This was a key battle in the Hundred Years' War, which pitted England against France over territorial claims and the succession of the French crown after Charles IV of France died without a direct heir.
King Edward III of England claimed he was the rightful heir to the French throne, which led to this long and complex war.
The English, through the use of trained and disciplined infantry armies, despite being outnumbered, managed to triumph at the Battle of Crécy, demonstrating the effectiveness of their military tactics during that period.
Furthermore, this conflict, along with others like the spread of the Black Death, shaped the political landscape of Europe.
In England, frequent parliamentary sessions were called by Edward III to secure funds for the war, which strengthened the parliament's role and laid the groundwork for a representative government.
In contrast, the French monarchy consolidated power, leaning towards a strong centralized government without a corresponding national assembly.
Therefore, the correct answer is A. The Battle of Crécy.
