What can make one part of a picture feel heavier than another part?

Correct answer: A large dark colour area

Direct answer: B is correct. Visual weight is the degree to which an element attracts the eye or seems heavy in a composition. Size and tone are important causes: a large area occupies more visual space, and a dark or strongly contrasting area usually attracts attention more than a pale area. Therefore, a large dark colour area can make one side of a picture feel heavier. A is less likely to create much weight because it is both small and light, although any mark can matter in a special context. C is empty and usually has little direct visual mass; it may influence balance through the surrounding objects but is not itself a heavy element. D is thin and faint, so it normally has low visual weight. The answer does not mean that colour alone always decides weight: size, darkness, contrast, position, and detail can work together. Memory cue: large and dark usually feel heavy; small and light usually feel light.
