Answer:
Men who are extremely ill and are very close to dying but have hope.
Step-by-step explanation:
Dylan Thomas's poem "Do Not Go Gentle into That Good Night" is a poem written about death and perseverance. The poem was dedicated to Thomas's father who was on the verge of death.
The given lines are from the 5th stanza of the poem where the speaker addresses the "grave men". Here, the use of the word "grave" can be taken in two ways- those who are on the verge of dying and knows their life is fading away. But also, the men who are saddened by their impending death but at the same time still have that burning flame of resistance, the passion to be alive despite the frail condition of their physical bodies.
Thus, the correct answer is the last/ fourth option.
