The correct answer is D. R2 sends a PIM join upstream towards R1 to join the source tree. See the full explanation below for the reasoning.
Question
In the exhibit, the routers in the network have a default PIM sparse mode configuration. R2 shows that R1 is the RPF next hop for the source, and R3 is the RPF next hop for the RP. Host1 is currently receiving multicast traffic for group 231.1.1.1. Host2 has come online and is attempting to join group 232.1.1.1. R2 has just received an IGMP message with the source and group addresses. Which step happens next so that Host2 can join the multicast group?
Exhibit

- BR2 sends a PIM join upstream towards R3 to join the source tree.
- CR2 sends a PIM join upstream towards R1 to join the shared tree.
- DR2 sends a PIM join upstream towards R1 to join the source tree.
