Answer: (A)

Verified step by step guidance

1. Understand that qualitative (categorical) data represent categories or groups, such as colors, types, or labels, rather than numerical values.
2. Recall that the goal of visualizing qualitative data is to show the frequency or count of each category clearly.
3. Consider the types of graphs: a bar chart displays bars representing the frequency of each category, making it easy to compare categories visually.
4. Recognize that a scatter plot is used for showing relationships between two numerical variables, so it is not suitable for categorical data.
5. Note that a box plot and histogram are designed for numerical data distributions, so they are not appropriate for qualitative data visualization.
