Which of the following best describes a visual expression of ideas in writing?

The correct choice is the one that identifies visual imagery as a means of expressing ideas through writing. Visual imagery refers to the use of descriptive language that creates vivid mental pictures in the reader's mind. It plays a crucial role in helping readers visualize scenes, characters, or concepts, thereby deepening their understanding and emotional response to the text.

While repetition emphasizes certain ideas or themes through the reiteration of words or phrases, and metaphor draws comparisons between unrelated things to highlight similarities, neither of these options primarily focuses on creating visual representations. Similarly, personification attributes human characteristics to non-human entities, which may create visual images but does not serve as a direct expression of visual ideas in writing. Visual imagery, on the other hand, specifically aims to evoke a clear picture and experience for the reader, making it the most fitting choice for describing a visual expression of ideas.
