The correct option is B Orchard
An orchard is an area of land where fruit trees (but not orange trees or other citrus trees) are grown. For example, "an apple/cherry orchard". Hence, Option D is correct. Among the rest of the options, park means a large public garden or area of land used for recreation, nursery means a place where young plants and trees are grown for sale or for planting elsewhere, yard means a piece of uncultivated ground adjoining a building, typically one enclosed by walls or other buildings. These do not express the intended meaning, hence incorrect.
