a. double bar graph. b. parallel graph.

c. stacked bar graph.

d. column graph.

c. stacked bar graph.

The following graph is an example of a d. column graph.

To determine the type of graph shown in the question, we need to understand the characteristics of each type of graph and compare them to the given graph.

a. A double bar graph is a graph that compares two sets of data side by side using bars. Each set of data has its own set of bars displayed next to each other. In the given graph, there is only one set of data represented, so it is not a double bar graph.

b. A parallel graph is not a commonly used term in graphing. It may be a specific type of graph not well-known or not commonly used. Therefore, it is not applicable to the given graph.

c. A stacked bar graph is a graph that displays different segments within a bar, representing different categories or subcategories of data. In this type of graph, the height of the stacked segments represents the quantity or value of each category. In the given graph, there is only one segment in each bar, so it is not a stacked bar graph.

d. A column graph, also known as a bar graph, is a graph that represents data using rectangular bars of equal width but varying heights. Each bar represents a category or a set of data. In the given graph, we can see columns (or bars) that represent different categories. Therefore, the graph shown is a column graph.

So, the correct answer is d. column graph.
