The statement that best explains the development of constitutional monarchy in England is:
The idea that a monarch’s powers should not be absolute was first made law in the Magna Carta, and with the Glorious Revolution it became the basis of England’s monarchial system.
This statement effectively highlights the significance of the Magna Carta in limiting monarchical power and lays the foundation for the later developments during the Glorious Revolution, which further entrenched the principles of constitutional monarchy.
