Which feature of the is constitution directly addressed a problem of articles of confederation

The following are the choices I found on the internet:

B. The Constitution created a government where each state was represented in Congress.

C. The Constitution created a federal government fully independent from Great Britain.

D. The Constitution created a federal government with three branches.

The answer would be letter D - The Constitution created a federal government with three branches. Each branch has distinct powers to carry out its responsibilities.

since most of current immigration into the u.s., both legal and illegal, is coming from latin america. it would be very difficult to imagine or rationalize a country my fellow citizens are trying desperately to flee into, would pose a threat to my prosperity or freedom. since the u.s. has a long history of intervention, but no record of permanent occupation, i would not feel oppression is the main objective.  

the largest free trade nation, along with the largest gdp in the world wanting to expand it's economic policy on us, and including us, could only be positive. the u.s. government has no interest in, or way of simply forcing american culture on us. and has no track record of it. other nations that adopted american social culture, or "americanization" did so voluntarily, mainly through the choice of allowing american businesses and u.s. citizens to come into their nations, as free operatives.
