Scale and Relative Size

The governing concept is proportion: the relative sizes of parts must be established before details are added. For this bottle, compare the neck width, shoulder transition, body width, and total height with one another. Setting these relationships first keeps the form believable and prevents later details from distorting it. Thus option C is correct; colour price, paper brand, and title do not determine the bottle’s structure.

In art, scale means the size of an object in relation to other objects, a person, or the surrounding space. Therefore, option A is correct. Colour intensity is a property of colour, while line thickness is a property of line; neither defines scale. Exam tip: If the question asks about size in relation to something else, look for scale.
