To determine which graph best represents your data, I'll need some specific information about the data you collected on the insect population over time. If you can provide the details of your counts (such as numbers of insects at various time intervals), I can help you analyze them and guide you toward the most appropriate graph representation.
If you have descriptions or characteristics of the graphs (A, B, C, D) available to you, please share those as well, and I can provide insights based on that information!
