Final answer:
The Magna Carta was indeed the first legal document to limit the power of the English monarchy, introducing principles like due process and trial by jury that underpin modern justice systems. The correct option is A.
Step-by-step explanation:
The statement about the Magna Carta being the first legal document to place restrictions and limits on the power of the English monarchy is TRUE. The Magna Carta, signed by King John in 1215, is a cornerstone in the development of constitutional governance. This great charter established the principle of limited government, asserting that the king's power was not absolute.
It guaranteed rights to the nobles and church leaders, such as the right to a fair trial by one's peers, which laid down the foundation for trial by jury and due process. These concepts were critical in the development of a clearer legal system in England and have had a profound influence on the juridical systems of the Western world, including the United States Constitution.
