Since the variable is qualitative and nominal, the data cannot be quantified or ordered in a meaningful way. Therefore, a frequency table can only provide the count or percentage of each category, and a pie chart is the best way to visually summarize the proportions of each category. The other options are not applicable because they pertain to quantitative or ordinal data.
