Why this is the correct answer:

1. Stark Contrast: The final stanza sharply contrasts with the rest of the ode, which is dominated by the speaker’s despair, grief, and inner torment.

2. Selfless Blessing: The speaker shifts focus from his own suffering to the “Dear Lady” (Sara Hutchinson), expressing a sincere wish for her happiness and peace.

3. Tender Imagery: Gentle and soothing imagery—like “gentle Sleep! with wings of healing” and waking with a “light heart”—replaces the stormy, tormented images of previous stanzas.

4. Emphasis on Joy: He blesses her with the joy he has lost, hoping it will “lift her spirit” and “attune her voice,” highlighting his enduring love and care despite his own dejection.

This final stanza underscores selflessness, tenderness, and the speaker’s capacity for love even amid personal despair.
