To determine which information is suited for display on a double line graph, we need to understand the purpose and characteristics of a double line graph.

A double line graph is used to compare and show the relationship between two sets of data using two different lines. It is commonly used to represent two different variables over time or related variables with a common domain.

Option A: This option, which presents the annual changes in Melody's height and weight from 5 to 10 years old, does not meet the requirements for a double line graph. Although it involves two variables, the time component (age) is the same for both variables, making it more suitable for a single line graph.

Option B: This option, which shows the number of Democrats and Republicans in the Senate during the past decade, does not involve a continuous variable over time. Instead, it focuses on discrete data points. Therefore, it is not suited for a double line graph.

Option C: This option, which depicts the monthly sales of two different types of cars during a one-year period, meets the requirements for a double line graph. It involves two variables (monthly sales) and a continuous time component (one year).

Based on the explanation above, the correct answer is C. The monthly sales of two different types of cars during a one-year period is suited for display on a double line graph.
