Why can a large shape become the main subject in a picture?

Because it attracts more visual attention

Size is an important way of creating emphasis in a composition. A large shape usually occupies more visual space and is noticed quickly, especially when smaller forms surround it. Because of this, the artist may use a large shape to make a person, object, or idea appear important. Placement, contrast, and colour also affect attention, so size is helpful but is not the only possible method.

Option A is correct because a large shape can attract stronger visual attention and become the main subject. A large form is not always a background; sometimes the background is large, but that is not a rule. Shape is related to attention, and a small shape can be important in some designs, but it does not automatically become the main subject. The question asks why size can create emphasis.
