The correct answer is B. To justify the American colonists' desire for freedom from British rule.
Explanation
The fragment of the Declaration of Independence written by Thomas Jefferson expresses the desire of the colonists to be independent and sets out real reasons to justify this desire because it argues that they are suffering "a long train of abuses and usurpations" by the British. He also expresses that in this situation of domination and bad government it is not only a necessity but "it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security" On the other hand, he expresses that the colonies now have "the necessity which constrains them to alter their former Systems of Government." and establish themselves as an independent nation. According to the above, the correct answer is B. To justify the American colonists' desire for freedom from British rule.
