Which of the following is a significant work authored by Voltaire?

Voltaire's "Candide" is a significant literary work that exemplifies the philosophical and satirical ideas deeply rooted in the Enlightenment. Published in 1759, "Candide" is a biting critique of optimism, particularly the notion espoused by the philosopher Leibniz that "all is for the best in the best of all possible worlds." Through the misadventures of its protagonist, Candide, Voltaire addresses issues such as the folly of blind optimism, the brutality of war, and the hypocrisy of religious and political institutions. This work not only showcases Voltaire's wit and literary talent but also embodies the spirit of questioning and challenging established norms characteristic of Enlightenment thought.

Other choices, while significant in their own right, are not attributed to Voltaire. "The Social Contract," for instance, is written by Jean-Jacques Rousseau, focusing on political philosophy and concepts of societal agreement. "The Leviathan," authored by Thomas Hobbes, delves into social contract theory and the necessity of strong governance. Lastly, "A Tale of Two Cities," penned by Charles Dickens, is a historical novel set during the French Revolution and explores themes of resurrection and duality. Each of these works reflects important ideas from their respective authors
