Answer:
B). Rhetorical question.
Step-by-step explanation:
Rhetorical questions exemplify one of the commonly employed techniques that helps influence the audience and evoke the critical thinking abilities of them. Such questions are not asked with an intent to be answered but rather to persuade or influence the audience to believe in a particular idea or claim.
As per the question, this excerpt from Henry David Thoreau's 'Resistance to Civil Government' employs 'rhetorical question'('shall we be content to obey them', 'shall we endeavor to amend them') to appeal and influence the audience to think and then display their 'resistance' against the civil government for the betterment of United States. Thus, option B is the correct answer.
