Which configurations must the engineer implement on CPE-1 and CPE-2?

Refer to the exhibit.

A network engineer is implementing multicast services on CPE-1 and CPE-2. CPE-1 must be configured as the preferred IGMP querier for the LAN segment. PIM-SM must be implemented on the LAN interfaces with an IGMP version that supports (*, G) joins only.

Which configurations must the engineer implement on CPE-1 and CPE-2?
A . On CPE-1:
interface GigabitEthernet0/1
ip address 10.0.12.129 255.255.255.128
ip pim sparse-mode
ip igmp version 2
On CPE-2:
interface GigabitEthernet0/1
ip address 10.0.12.130 255.255.255.128
ip pim sparse-mode
ip igmp version 2
B. On CPE-1:
interface GigabitEthernet0/1
ip address 10.0.12.130 255.255.255.128
ip pim sparse-mode
ip igmp version 3
On CPE-2:
interface GigabitEthernet0/1
ip address 10.0.12.129 255.255.255. 128
ip pim sparse-mode
ip igmp version 3
C. On CPE-1:
interface GigabitEthernet0/1
ip address 10.0.12.130 255.255.255.128
ip pim sparse-mode
ip igmp version 2
On CPE-2:
interface GigabitEthernet0/1
ip address 10.0.12.129 255.255.255.128
ip pim sparse-mode
ip igmp version 2
D. On CPE-1:
interface GigabitEthernet0/1
ip address 10.0.12.129 255.255.255.128
ip pim sparse-mode
ip igmp version 3
On CPE-2:
interface GigabitEthernet0/1
ip address 10.0.12.130 255.255.255.128
ip pim sparse-mode
ip igmp version 3
