Which line from Frost's poem suggests that winter cannot destroy the cycle of life?

The line suggesting that winter cannot destroy the cycle of life embodies the theme of resilience and rebirth in nature. It conveys the idea that although winter may bring death or dormancy, it ultimately does not prevent the renewal of life that follows. This perspective acknowledges the harshness of winter while simultaneously reinforcing the concept that life persists through cycles. When examining the other choices, they might hint at aspects of life and transformation, but none encapsulate the comprehensive concept of rebirth following winter as effectively as this line does. The focus on death leading to rebirth indicates a continuous and unbreakable cycle of life, central to understanding the interplay of seasons and the natural world.
