The answer is B: "Oh, flower gathering? That is why your feet seem so glad and your anklets jingle so merrily as you walk."
Explanation for each option:
(A) "I see, you don't wish to stop; I don't care to stay on here either." - This quotation does not effectively illustrate the claim that Amal imagines people to be carefree. It suggests a mutual desire to move on, but it doesn't convey a sense of carefree engagement in work or chores.
(B) "Oh, flower gathering? That is why your feet seem so glad and your anklets jingle so merrily as you walk." - This quotation effectively illustrates the claim. Amal perceives the flower seller's daughter as being joyful and carefree while engaged in her work, as indicated by the gladness in her feet and the merry jingling of her anklets.
(C) "I'll pay when I grow up-before I leave to look for work out on the other side of that stream there." - This quotation reflects Amal's future aspirations and willingness to work, but it does not illustrate the idea of seeing others as carefree in their current activities.
(D) "Wish I could be out too. Then I would pick some flowers for you from the very topmost branches right out of sight." - While this shows Amal's desire to be outside and engage in an activity, it does not directly illustrate his perception of others being carefree in their work or chores.
