Answer:
Emphasizing pieces of scenery is the correct answer.
Step-by-step explanation:
Lighting is one of the elements used in arts. Its intention is to manipulate shadows and light to emphasize public's attention on something or someone in particular.
Scenery is defined as all the items used in a theatrical production, from the most common thing (a mop or a piece of paper) to the most elaborated things (complex structures or paintings). Lighting is used to emphasize these elements, meaning that they are more important than the ones that surround them.
