The Romanticism movement could best be described as a rejection of the classicism movement. Classicism emphasized order, rationality, and balance, whereas Romanticism celebrated individualism, emotion, and nature. Romanticism rejected the ideals of the Enlightenment and instead celebrated the irrational, the exotic, and the mystical. Romanticism also emphasized the beauty and power of nature, and many Romantic artists and writers sought to capture the awe-inspiring power of natural landscapes in their works. So, the correct option is "rejection of the classicism movement."
