Answer:
C). Place the graphic close to the point where it is mentioned.
Step-by-step explanation:
The advice that Ana must be given would be 'to place the graphic i.e. 'bar graph' close to the point where it is mentioned' as it would help in illustrating the growth in the productivity due to the installation of softer lighting more effectively. It would help in presenting the data visually and make it more comprehensive. Placing the chart after two pages would not create any impact but rather clutter the writing. Thus, option C is the correct answer.
