Refer to the exhibit. An engineer must implement VXLAN with anycast gateway. To accomplish this, an engineer must set up PIM Source-Specific Multicast for host reachability. Which IP address must be applied to interface loopback1 to accomplish this goal?
To implement PIM Source-Specific Multicast (SSM) for host reachability in a VXLAN configuration with anycast gateway, the loopback address used should be unique and able to communicate with other RPs. The correct subnet for the loopback address should be a /32 to ensure it is unique and represents a single host. In this case, the appropriate IP address to use for interface loopback1 is 10.10.0.1/32.

absolutely terrible question, PIM SSM doesn't require RP
Yeah awful
moreover you need to have 2 loopbacks for pim-anycast RP, one of them has anycast RP configured, another one has unique IP for communicating with other RP switch, so basically any of the A,B,C options could be correct
B is ok
as per te doc https://www.cisco.com/c/en/us/support/docs/ip/ip-multicast/115011-anycast-pim.html
