Correct answer: C
The Pareto chart of effects visually displays the magnitude of each effect relative to a significance threshold (the red line at 2.1). Any effect whose bar extends past this line is statistically significant. According to the chart, the bars for A (4.5), B (3.8), D (2.9), and the interaction AB (2.2) all cross the 2.1 threshold. The effects C (1.5) and AC (0.8) do not, so they are not considered significant.
