To determine the minimum value selected in an unlabeled dot plot, you would need to look at the data points represented by the dots on the plot. The minimum value is the lowest number represented on the plot.
Since I don't have access to the image, I'm unable to provide the exact minimum value. However, you can find the minimum by visually inspecting the plot for the lowest dot present.
If you have specific numbers from the options provided, you can check which is the smallest value among them. Based on your options, the minimum value could be either 0 or 1, depending on what is shown in the plot.
