D. cardinal directions

Explanation:

The cardinal directions are the four basic sides of the world. They are used in every segment of the human lives, and in wide variety of fields. The four cardinal directions are east, west, north, and south. They are further divided for more precise defining of the space and things, initially into southwest, southeast, northwest, and northeast, and later even in more detail as south-southwest, south-southeast, north-northwest, and north-northeast. Each side has something associated with it, with the east usually being associated as the side from which the sun rises, west as the side where the sun sets, north being associated with cold, and south associated with warmth.
