D. Rural peacefulness.
With simple words, the author conveys that there's an importance attached to the wheelbarrow and describes a whole scene in a brief moment in time. The wheelbarrow is glazed with rainwater (it has drops of waters in it) which suggest that perhaps, it had rained recently. The focus on something as simple as this conveys a sense of peace. Furthermore, the final stanza "beside the white chickens" suggests that the main object is in a rural setting. The color of the chickens also communicates something, as white is a color that conveys peace.
