Answer:
The correct answer is option A. to emphasize the seriousness of colinists' reasons for declaring independence.
Step-by-step explanation:
Thomas Jefferson decided to introduce the idea that one does not change a government for "light" causes to make it absolutely clear that what they were doing was what they had to do. They had tried to reach peaceful agreements with the British Parliament (such as the Petition to the King), but they were not heard. Their individual and citizenship rights had been violated and they were not protected, and those were heavy causes (not light causes) that backed up their decision to declare independence. They would not want to change the government out of nothing, that's what it means.
