Answer:
Answer is Option D: Both the U.S. Constitution and state constitutions divide power between three branches of government.
Step-by-step explanation:
The Constitution is based on the system of federalism in which power of the three branches: legislative, executive, and judicial are divided between the national and he state government. This is the similarity between the two.
State Constitutions are usually lengthier and detailed than federal Constitution. So, option A is incorrect. The State Constitution is more open to amendments, making Option B incorrect. Also, local government must be granted power by the state. So, option C is also incorrect. Thus, the similarity is Option D.
