Answer: B. Mention the graphic in the text of the report.
The text of the report should describe or discuss the justifications of the graphics.
Explanation:
Graphics should be included inside the report, rather than only in the appendix, if they are important for discussions and presentations in the report.
Graphics can be created in colors in the report, especially if the reports are to be printed in colors version. However, if the report is to be printed in black and white only, the graphics should also be in black and white only so that the printing resolution is clear.
Titles of the graphs, x-axis and y-axis, together with the range should be clearer shown together with the graphics for the readers' understanding.
