To apply the gold accent 4 lighter 80 percent fill color to the shape, what must be clicked?

To apply the gold accent 4 lighter 80 percent fill color to a shape, it is essential to navigate through the Drawing Tools Format tab and specifically utilize the Shape Fill button. Selecting the fill color involves not just accessing the Shape Fill button but also ensuring you choose the right color from the available options. In this case, selecting the eighth option in the second row directly corresponds to the gold accent 4 lighter 80 percent fill color; this precise navigation ensures that the correct shade is applied effectively to the selected shape.

Other options may not lead to the desired fill color.

Thus, the correct answer highlights the most direct and accurate method for achieving the specified color fill for the shape.
