Explanation:

A pie chart represents data as slices of a circle, showing proportions of a whole. Here, the graphic displays percentages (49% for 0 - 2 children, 42% for 3 or more, 9% don't know) that sum to 100% (49 + 42 + 9 = 100), fitting the pie chart's purpose of showing relative frequencies. A dot plot uses dots for individual data points, and a bar graph uses bars for categories; this doesn't match those. So the correct type is a pie chart.

Answer:

Pie chart (the option would be the one labeled "Pie chart" among the choices, e.g., if the options are as in the image: the pie chart option is the correct one, so the answer is the pie chart option, like "Pie chart" (assuming the radio button for pie chart is the correct choice here based on the data representation as percentages summing to 100%).)
