To approach this question, consider what each plot type is typically used to show in data visualization.
Option a: 'a. box; scatter' A box plot is great for showing distribution summaries (quartiles, medians) and potential outliers, while a scatter plot is used to display relationships and possible clustering, not a description pairing that fits the blank as stated. This pairing misaligns the primary purposes.
Option b: 'b. scatter; line' A scatter plot is indeed well-suited to reveal clusters by plotting individual observations in two dimensions, highlighting groupings or patterns. A line plot is commonly used to display a sequence over time, showing trends. This combination accurately matches the typical uses of these plots for the blanks in order.
Option c: 'c. heatmap; pie' A heatmap visualizes values across two dimensions via color intensity and can illustrate patterns or clusters in a matrix, but a pie chart conveys proportional composition rather than trends over time, so the second blank would be inappropriate for trends over time.
Option d: 'd. histogram; bar' A histogram portrays the distribution of a continuous variable, while a bar chart compares discrete categories. Neither is primarily designed to depict trends over time, so this pairing does not fit the intended blank placements.
In summary, option b aligns with the conventional roles of the plots: scatter for clusters and line for trends over time, while the other options pair plot types in ways that do not match their common uses.
