Answer:
C). Traveling is a freeing experience that allows for independence and self-reflection.
Step-by-step explanation:
Whitman's 'Song of the Open Road' primarily explores the theme of 'freedom and liberty.' The speaker describes an embarking trip or an adventurous journey that he initiates towards an open road(unnamed/unknown destination). He calls it a freeing experience as he feels 'Healthy, free' and 'the world before him' and without any pressure or troubles. He can just relax on the open road and do anything he wishes to as 'the little things begin to matter less and less.' Thus, it offers an opportunity to look into ourselves and introspect. Hence, option C is the correct answer.
