Option A.
Step-by-step explanation:
In the 14th century, Parliament in England evolved in terms of involving different estates of the realm.
Membership in Parliament expanded to include representatives elected by the vassals of the king's vassals, and selected towns could send representatives to speak for the interests of merchants.
This new body represented the interests of the nobles, clergy, and commoners.
The changes in Parliament were initiated by Edward I, who called his first Parliament in 1275 and continued to convene it during his reign.
The increased frequency of Parliament sessions during the Hundred Years' War strengthened Parliament's role in England and helped to shape the House of Lords and the House of Commons.
