Final answer:
The best fitting additional clause for the list from the passage emphasizing the fight for freedom and resistance against tyranny is 'E. If we desire independence.'
Step-by-step explanation:
The clause from the list that would best fit into the passage is 'E. If we desire independence.' The passage emphasizes the importance of fighting for liberty, enduring struggles for the sake of freedom, and not giving up in the face of tyranny. This theme is consistent with the other lines in the list, which highlight the determination to preserve privileges and engage in a noble struggle. The desire for independence aligns with these sentiments and the general tone of historical determination found in the referenced excerpts from various speeches and documents advocating for liberty and self-governance.
