a. The info member of Node 1, referenced from pointer C
b. The info member of Node 2, referenced from pointer B
c. The next member of Node 2, referenced from pointer A
d. The next member of Node 4, referenced from pointer C
e. Node 1, referenced from pointer B
f. The back member of Node 4, referenced from pointer C
g. The back member of Node 1, referenced from pointer A
Explanation / Answer
a. C->next->info
b. B->prev>info
c. A->next
d. C //since C is the next node of node 4
e. B->prev->prev
f. C->prev->prev
g. A->prev
