Final answer:
The excerpt describing a grievance from the Declaration of Independence is the one accusing King George III of dissolving Representative Houses that opposed his actions.
Step-by-step explanation:
The correct excerpt that represents a grievance of the American colonists included in the Declaration of Independence is: 'He has dissolved Representative Houses repeatedly, for opposing with manly firmness his invasions on the rights of the people.' This passage directly addresses one of the many specific complaints that the colonists had against King George III, whereby he is accused of dissolving legislative bodies that stood up for the colonists' rights.
The other excerpts provided either express the fundamental democratic principles of the document or the assertion of independence but are not direct grievances against British rule.
