Final answer:
The correct answer is option B. Through individual moral awakening and nonviolent resistance.
Step-by-step explanation:
Henry David Thoreau believed that justice can be achieved through individual moral awakening and nonviolent resistance. This approach is reflected in his essay titled 'Civil Disobedience' where he discusses his refusal to pay a poll tax due to his opposition to the Mexican-American War and slavery.
He advocates for passive resistance, a concept that influenced later figures like Gandhi and Martin Luther King Jr., suggesting that just individuals resist unjust laws through nonviolent means. Thoreau's stance emanates from his belief in personal freedom and his critique of governmental overreach as written in his works, including 'Walden'.
For Thoreau, the epitome of upholding justice was not through enforcement of laws, military force, or economic policies, but by individuals taking a stand against what they deemed unjust. His notions support a more philosophical and proactive approach that relies on the conscience of the people rather than authoritarian control or systematic reforms.
