饼图显示了关于一些学生最喜欢的超级英雄的调查结果。表格中的一个数字被墨迹遮住了。

超级英雄	学生人数	类别
神奇女侠	超过一半	A
钢铁侠	30%	B
雷神	[墨迹]	C
超人	10%	D

在饼图的方框中填入 A、B、C 和 D，以表示表格中给出的数据。

1. Identify the largest sector (Category A)

Wonder Woman (Category A) is 'More than half', which means $> 50\%$. The largest sector in the pie chart is clearly more than half the circle. So, the largest sector is A.

2. Determine the percentage for Thor (Category C)

The total percentage must be $100\%$. Since A is $> 50\%$, B is $30\%$, and D is $10\%$, the sum of A, B, and D is $> 90\%$. Therefore, C must be $< 10\%$.

3. Assign the remaining categories to the sectors based on their sizes

We have B ($30\%$), D ($10\%$), and C ($< 10\%$). Comparing their sizes:
$30\% > 10\% > (< 10\%)$
So, B is the largest of the remaining three, D is the next, and C is the smallest.
Matching to the pie chart:

• Medium sector (bottom right) = B
• Second smallest sector (top right) = D
• Smallest sector (top, next to vertical line) = C
