In a circular doubly linked list, both insertion and deletion operations are uniform across all positions, including the first and last positions. This is because the list is circular, meaning the last element points back to the first element, and the first element points back to the last element, making operations like inserting or deleting from the last position not a special case. The precede reference of the last node points to the second-to-last node, not null, and the next reference of the last node points to the first node, not null, making options A, C, and D incorrect.
