How can art give a message without words?

Correct answer: Through images, colours, and signs

The governing concept is visual communication, in which meaning is conveyed through what people see rather than through spoken or written language. An artist can combine images, colours, shapes, facial expressions, gestures, and familiar signs to guide the viewer toward a message. For example, a red signal may warn people, while a carefully drawn image can show friendship, danger, or environmental concern. Therefore, option D is correct because images, colours, and signs can communicate directly to the eye. Options A and B describe activities or methods that do not themselves create a visual message, and option C merely describes silence, which does not automatically communicate a specific idea.
