What were citizens of the polis expected to do? A. Obey the king's laws B. set up schools for all people C. elect representatives to the assembly D. fight to defend the polis. I NEED HELP ASAP GIVING 25 POINTS AND BRAINLIEST TO ANSWER

I believe all of the answers are correct.

Explanation:

The polis became very democratized following the fall of the Assyrian empire, and school eventually became required. The king's laws were necessary to obey because the kings were usually elected and were responsible for making choices important in the development of Greek society and culture. Obviously, the Greek poleis had sophisticated defense systems, especially in Spata, so D is correct as well.
