B. Bob
C. Chio
D. Dmitri
E. Ehab
F. Fritz

Explanation 解释
The correct answer is Chio.
正确答案是 Chio。
In order to find the beaver whose picture gets seen by most beavers, you have to count the beavers that are at most two steps away. The beavers that are one step away are those on whose page the pictures will be posted and the beavers that are two steps away are those who can see these pages.
为了找出其照片被最多海狸看到的那只海狸,你得计算出距离它最多两步的所有海狸。距离为一步的海狸是指那些照片会发布在其页面上的海狸,而距离为两步的海狸则是那些能看到这些页面的海狸。
当然,任何一只海狸只能算一次。
The following table shows the names of these beavers as from the starting point of each beaver.
