The correct answer is B. Bidirectional PIM. PIM-BIDIR is specifically used for many-many and allows for easy scaling. The downside is since it doesn't use SPT and as such can be sub-optimal from a routing standpoint, but as you can see in the diagram that is not an issue here due to the lack of complexity.
