how many warnings can you get and what happens if you get past your limit warnings on this thing lol?

I don't know the exact number of warnings but, if you get too many you could get banned from the website.

Explanation:

I believe the answer is: B. their development of nuclear weapons program

Since north Korean was't involved in any international peace agreement,  other east Asian countries view it as a threat to their national security.

In order to retaliate, many countries led by the united states imposed sanctions to north Korean companies in order to restrict their economy and slowed down the development program.
