Not to be a pain, but I have to clarify this a little. If you can understand what I'm saying, you might be able to impress your teacher.
If you consider just the range of star sizes, the sun is *way* below average. If you consider its position by the *number* of stars larger and smaller, it is probably somewhat *above* average. This is because the smallest stars are the most populous. The giants are relatively rare.
As for the range of sizes, stars may go as small as 1/10 the diameter of the sun, (not counting white dwarfs and neutron stars), but there are stars 1600 times *larger* than the diameter of the sun. You can see that this puts it far below the halfway point when you look at it that way. But again, those really big stars are very much in the minority. Red dwarfs, which are from about 1/10 to 1/2 the sun's diameter, probably outnumber any other size/color grouping.
So A or C could be right, depending on what you choose as the criterion for comparison.
