In which scene can a dark shade of a warm colour be useful?

Correct answer: Deep shadows on a brick wall

The governing concept is the expressive use of warm and cool colours with value changes. Deep red, burnt orange or brown can represent the brick colour and strong shadows on a wall, giving the surface weight and depth. A clear sky and a snowy lake are usually associated with cool blues and whites, while a bright green field is not the best match for a dark warm shade. Thus option A is correct.
