The correct answer to which is the connotation of the word "empty" in that excerpt is C. The area looks barren.
The poem "The Snow" - also known as "It Sifts From LeadenSieves" - by Emily Dickinson (1830-1886) describes the movement and the effects of snow in a lyrical and beautifully metaphorical way. She captures how it falls and covers the the road, the fences and the landscapes, transforming them from a familiar vision into something different and strange in a romantic way.
In the mentioned excerpt, the snow has covered the fields where the harvests were in summer, full of live and vegetation, turning them into an "empty" or barren space. The memories of the plantation in summer have been replaced by an empty field covered in snow, rendering it ghostly and barren.
