When can broken proportion be expression rather than a mistake in a painting?

When it purposefully intensifies feeling, symbol, or message

The governing concept is purposeful distortion. Proportion normally helps viewers judge the relative size and relationship of parts, but an artist may deliberately enlarge a hand, stretch a figure, or reduce a body to emphasize power, fear, grief, importance, or symbolism. The distortion becomes expressive when it supports the work’s idea and is used consistently or knowingly. Therefore, option A is correct. Option B describes arbitrary error rather than a communicative decision. Option C confuses artistic freedom with carelessness, and option D is unnecessary because expressive distortion can occur in a painting with a clear subject. Intention and effect help distinguish a meaningful choice from an accidental mistake.
