Bunuel , the top image will not open in two different browsers. I can open the image in the spoiler. Just thought you might want to know. (It's a easier to follow the prompt when the picture is directly above the question. No scrolling needed. )

From A to C there are 2 different paths, and from C to B there are 4 different paths. Now, for each of the 2 paths from A to C, there are 4 paths from C to B. So answer should be 2*4 = 8
