Answer:
D). It is important to have dreams throughout your life.
Step-by-step explanation:
The given poem titled 'He Had His Dream' authored by Paul Laurence Dunbar primarily explores the central idea of staying hopeful and optimistic throughout one's life.
It displays that despite being poor, the man did not lose hope and kept working hard in hope and aspiration for better days to arrive in his life. This message is reflected through the descriptions like 'hopeful hue,' 'tinctured every passing beam,' 'saw through every cloud a gleam, he had his dream,' etc. It substantiates how hope is the light that keeps an individual alive throughout life and thus, everyone must stay positive and hopeful in life. Hence, option D is the correct answer.
