Selected Answer: B
Given that larger (more extreme) brownouts/blackouts are increasing in frequency while smaller events decrease, the distribution suggests heavier tails (i.e., more extreme outliers). That behavior is captured by kurtosis, which measures the “tailedness” of a distribution—how prone it is to producing large outliers. Hence, the best answer is: B. Kurtosis
