Answer:
C). The refrains emphasize the importance of resisting death.
Step-by-step explanation:
The excerpt from "Do not go gentle into that good night" by Thomas Dylan where the speaker preaches the brightness and goodness of life that could come only after resisting death. The poet is distressed with his father's deteriorating health and pleas his father to resist death and enjoy the brightness of life. The poem is a message and encouragement to all old age people to battle death and reform their fate and not offer their consent to death so easily("do not go gentle into that good night"). Thus, the refrains emphasize the importance of resisting death and exemplify the significance of being alive and enjoying the beauty of life and achieving their wishes.
