Although you did not include the options for this question, we can answer the following.

During the rule of King Edward I, the document that provided parliament with the final say on levying taxes was the Confirmation of Charters.

This was an important document in the times of King Edward I of England.  The Confirmation of Charters was issued in 1297 and was added to Magna Carta. It was a document that the King wanted to create with comments that could not be added to the original Magna Carta. King Edward considered that a new document was needed to negotiate some issues with the English noble barons.
