Both the magna carta and the petition of right addressed issues related to war. property. taxation. religion.

The correct answer is TAXATION.

Explanation:

Magna Carta, also known as the Great Charter, was signed by john Lackland in 1215. He was forced to sign because the Barons rebelled against his taxation abuses. Moreover, clause 12 clearly states "no taxation without representation".
