Since we have alternatives to compair, they can help we to guide the answer.
The greatest group is the first one: 0 - 4 with 43%.
50% would be half, so the part of this group is a little less than half the circle.
The graph on A show 0 - 4 as half the circle, which is not true, so we can exclude alternative A.
Also, alternative B show 0 - 4 as 1/4 of the circle, which would be 25%. Also, which group in alternative B has the same size, which would mean all of them would be close to 25%, which is not true, so we can also exclude alternative B.
Now, looking at the s
