after you plot your data points, what kind of line should you draw for the data points?
a horizontal lines representing the average values
a smooth, possibly curved, line that you judge to come closest to all the points
a vertical line representing the midpoint of the data

A smooth, possibly curved line that you judge to come closest to all the points i.e, best fit line.

Explanation:

Line of best fit is a line through a plot of data points that best expresses the relationship between those points. The statement 'A smooth, possibly curved line that you judge to come closest to all the points' defines the best fit line.

The other options are incorrect because we do not represent the plot of data points by horizontal or vertical lines representing their average/ midpoint values.

the second one and the forth one are in the purple because they are opinions and the rest are in the yellow

explanation:

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
