What can be a major basis for identifying an artist's style through line and expression?

Correct answer: Movement, pressure, break, and flow of line

Direct answer: An artist’s style can be studied through the movement, pressure, breaks, and flow of the lines, so A is correct. Style is a repeated way of seeing and making marks. One artist may use calm, continuous, delicate lines, while another may prefer forceful, broken, rapid, or strongly varied strokes. These habits can reveal energy, control, sensitivity, and expressive preference, although style should be judged from the artwork as a whole rather than from one isolated mark. B is wrong because canvas size alone does not show how the artist draws. C is wrong because the same subject can be treated in many different styles. D concerns cost, not artistic language. A identifies observable behaviour in the lines themselves. Memory cue: style lives in the artist’s repeated way of making marks, not merely in the subject or frame.
