Answer:
The correct answer is option B. "use of photographs, bar charts, line charts, and other visuals throughout the document".
Explanation:
The use of any pictorial representation that helps to explain, clarify or support an idea in a document is considered a visual aid. Visuals could be very effective, as most of the people remember a picture for longer than an explanation in a text. When photographs, bar charts, line charts, and other visuals are used throughout the document it is considered that it is a visually intense document. These type of documents are very attractive, particularly for academic purposes.
