In which condition can shape proportion be intentionally kept unnatural?

To increase expression, fantasy, or caricature

The governing concept is intentional distortion: proportion may be changed from observation when the artistic purpose is expressive rather than technically accurate. Option A is correct because exaggerating a head, hand, feature, or other shape can strengthen emotion, humour, fantasy, symbolic meaning, or caricature. The distortion is successful when it is controlled and supports the intended message. Options B and D require dependable measurement and realistic relationships, so unnatural proportion would reduce accuracy. Option C also depends on standard recognition and consistent dimensions; changing the sign’s proportions could confuse its meaning. Therefore the issue is not whether proportion is objectively normal, but whether the chosen proportion serves the purpose of the design.
