Explanation
Correct answer: D.
Choice D is correct. An appropriate model should follow the trend of the data points and should have data points both above and below the model. The scatterplot shows that the data points have an increasing trend that is curved. Therefore, an appropriate model should be an increasing curve with data points both above and below the model. Of the given choices, only the model in choice D is an increasing curve with data points both above and below the model.
Desmos solution:
Note: Compare the two curves to the data; choice D's curve has points both above and below, while choice C's curve has all points below it.

Why the other choices are wrong
Choice A
Choice A is incorrect. Since the trend of the data points isn't linear, a line isn't the most appropriate model for the data.
Choice B
Choice B is incorrect. Since the trend of the data points is increasing and isn't linear, a decreasing line isn't the most appropriate model for the data.
Choice C
Choice C is incorrect. All the data points are below the model shown in this graph.
