Which option shows both temperature contrast and complementary contrast together?

Correct answer: Yellow-orange and blue-violet

Temperature contrast is produced by pairing a warm hue with a cool hue, while complementary contrast uses colours opposite each other on the colour wheel. Yellow-orange is warm and blue-violet is cool; they occupy opposite, or near-opposite, positions on the wheel and therefore satisfy both conditions. Option C is correct. The other pairs are neighbouring analogous hues and do not provide strong complementary opposition.
