The best scale and interval would the 0 to 4 with intervals of 0.2  Since all numbers in this set have decimals in them, a scale of 2 or 1 would not be specific enough.  Also, a scale from 1 to 4 would not show 2 of the data points.  Therefore, by showing all of the points with an appropriate scale, the last option is the best option.

Hope this helps!

Answer:

It is in fact, the 0 to 4 with intervals of 0.2  Since all numbers in this set have decimals in them, a scale of 2 or 1 would not be specific enough.  Also, a scale from 1 to 4 would not show 2 of the data points.  Therefore, by showing all of the points with an appropriate scale, the last option is the best option.
