If we do not have a header node, why is removing the first node of a linked list a special case?
A. The first node is the most complicated node of the entire linked list.
B. It complicates the insertions that might take place afterwards, since insertions take
place at the beginning of the linked list.
C. If we don’t do it properly, there is memory leak for the rest of the nodes in the list; if

D. We need to move the start pointer when removing the first node, but not when removing any other nodes.
