Answer: The organizational structure used is D. spatial order.
Step-by-step explanation: There are different ways in which a text can be organized. One type of organizational structure is spatial order, which consists in presenting elements as they are located in space. In other words, a text that shows spatial structure arranges elements in the exact way they appear in a particular place; therefore, prepositions and words denoting cardinal points are very common when using spatial order. In the passage provided, the text has been organized in relation to the location of the elements in the living room. In that way, words such as "south", "east", "right" and "west" show that the organizational structure used in this passage is spatial order.
