C)anecdote - your answer, I assume this was what you were looking for by the word "which", and having recall coming across a similar question.
Before 1789, the U.S. had been ruled by the Articles of Confederation (1781) in fear of govt. abusing power (like British rule). In 1787, it was obvious that they needed a perfect Union and so, while protecting the independence of states, the Articles of Confederation didn't describe the powers of a federal chief executive nor a judicial system. The creation of our Constitution and present form of government was informed by these and other considerations that arose during the years of the Confederation.
The correct answer would be C. THis is because if it is written as (it's) it is a contraction for (it is).
