D) relates to another variable; time- series graph

Question

A time-series graph is typically used to show how a variable evolves over time. It is a line graph that plots the data points on a timeline. Therefore, option C is the correct answer. Option A is not a valid match because a pie chart is used to show how different categories relate to each other, not how a variable relates to another variable. Option B is close, but a cross-section graph is usually used to compare different groups at a single point in time, not to show how a variable evolves over time. Option D is partially correct, but it is not specific enough because it does not indicate the type of graph that should be used.
