n, m +n, and m*n are the nodes linked lists in the representation. Therefore option B,C, and D is correct.
The number of nodes in all the linked lists in the graph's linked list representation depends on the graph's characteristics.
In a fully disconnected graph, each node has no edges, so the total number of nodes in the linked lists is simply equal to the number of edges (option B).
In a connected graph, the total linked list nodes are greater than the number of edges but still less than the product of the number of nodes and edges (option C).
For a fully connected graph, the total linked list nodes exceed the number of edges and can reach up to the product of the number of nodes and edges (option D).
The answer can be any combination of options B, C, and D based on the graph's structure.
