I don't see all of the answer choices, but those two lines definitely maintain the lighthearted tone in the poem. wordsworth is describing a positive experience he had with nature, so i would pick whichever choice that says those lines express his happiness.
Wordsworth was a lover, admirer, and worshiper of nature. His poems echo the positivity, serenity, and beauty displayed through nature. The poem "I Wandered Lonely as a Cloud" too exemplifies just another compliment and admiration to nature. He demonstrates that nature acts as a soothing force that adds pleasure and joy. The lines “heart with pleasure fills, / And dances with the daffodils” personifies daffodils to symbolize the excitement and pleasure offered by nature that aids to escape solitude.<em>The 'pensive' mood of Wordsworth sets a positive and vital tone to the poem juxtaposing the beginning that describes 'loneliness' and 'solitude'. Thus, these lines shift the tone and mood from negative and pessimistic to positive and optimistic through the beauty spread around by daffodils.</em>
I don't know if you have this options but if you have this option I did the one that starts with though a form of the sweet treat dates back to the 1400s...
