Final answer:
A line graph is the best choice for illustrating how the average daily temperature changes over the course of a month because it clearly shows trends and changes in time series data. Option C is correct.
Step-by-step explanation:
The best way to show how the average daily temperature rises and falls over the course of a month would be through a c. line graph. This type of graph is particularly useful for displaying changes over time, known as time series data.
With a line graph, each point on the graph represents the temperature on a given day, and when these points are connected in chronological order, it forms a line that clearly illustrates the temperature trends throughout the month.
A bar graph could be used to show temperature data, but it is more suitable for comparing the temperature for different days or weeks as separate categories rather than showing the flow of temperature changes over time.
A pie chart is not suitable in this case because it is designed to show parts of a whole and does not handle time series data well. Lastly, a 3-2-1 organizer is a type of graphic organizer that helps organize thoughts or concepts and does not serve the purpose of displaying numerical data changes over time.
