Why is it important to understand positive shape and negative shape together?

Because the main object and surrounding empty space together make composition

Positive shape is the main visible object or form in an artwork, while negative shape is the surrounding or enclosed empty area. Neither is useless: both are seen together and both affect how the composition feels. The empty space can define the edges of the object, separate forms, create balance, and help the main subject stand out. Looking only at the object may cause the artist to miss important relationships in the design.

To answer, compare the choices with this relationship. Negative shape is not always wrong, and positive shape is normally visible. Both shapes clearly relate to composition because their sizes, positions, and boundaries influence balance and focus. Thus option A is correct: the main object and the surrounding empty space work together to form the composition.
