The correct answer is A. A graph or table
Step-by-step explanation:
In writing, a technical manual is a type of expository that aims at explaining users or individuals how to complete a process or task. Due to this, manuals often arrange information using letters or numbers along with different graphs or tables, because these allow the writer to display information in a visual way which is in most cases easier to understand than texts. This implies an author of a technical manual would use graph or tables to include numerical data rather than expository writing, technical language or a persuasive speech because graphs and tables are more suitable for displaying information that is difficult for the reader to understand as visual elements are included.
