In the poem The Stone, the woman has been carrying deep grief, likely connected to the loss of a loved one. Throughout the poem, her engagement with the stone serves as a channel for processing this grief. When she finally sighs at the end, it symbolises the release of pent-up sorrow - the moment when accumulated emotional pain is finally let go.
A sigh in literature often represents a physical manifestation of emotional release. It is the body's way of exhaling tension, sadness, or burden that has been held inside. The woman's final sigh marks the point at which her grief, having been contained and carried for so long, is finally expressed and released. It is a moment of catharsis - not a resolution of her loss, but an unburdening of the weight it placed on her.
The other options do not capture this emotional significance. The end of a carving process is a literal, physical interpretation that misses the symbolic depth of the moment. The release of a lover's spirit imposes a supernatural reading that the poem does not establish. Readiness to remarry projects a practical, forward-looking attitude that contradicts the poem's focus on grief and emotional reckoning. The sigh is about sorrow leaving the body, not about new beginnings or completed tasks.
