This would give you three graphs, one centered on "A", one centered on "B"
and one centered on "C". This would be returned in a list with three
elements. Since you specified only "A" for graph.neighborhood, it will
return a list of one element only, but you still need to refer to the first
element with [[1]] to get the actual graph.

What makes you think that? graph.neighborhood will return the vertex and its
first-order neighbors only:

B C

And I expect only
A C
A B
Should be output...
