The correct answer is B. Through dialogue and visual images
Step-by-step explanation:
A graphic novel is a type of book or document that tells a fictional or non-fiction story through comics. This means different from regular novels or stories, graphic novels include mainly images and text that is presented through speech balloons during dialogues. Besides this, in graphic novels most elements are presented visually this includes characters, main actions, sound effects, settings, among others. According to this, in a graphic novel, a story is told "through dialogue and visual images" rather than only text as it occurs in regular stories or novels.
