Which two statements about IGMP Querier are true? (Choose two.)
A. In IGMPv3, the Querier election process uses a multicast routing protocol
B. A Querier uses 224.0.0.1 as the destination address for general queries
C. In IGMPv2, the router with the highest IP address is elected as the Querier
D. A Querier running IGMPv2 or IGMPv3 supports group-specific query messages
E. In IGMPv2, the router with the lowest MAC address is elected as the Querier
F. A Querier running IGMPv3 sends the group-specific and group-and-source-specific queries to 224.0.0.22
C is incorrect. B and D are correct

Query messages are used to elect the IGMP querier as follows:
When IGMPv2 devices start, they each multicast a general query message to the all-systems group address of 224.0.0.1 with their interface address in the source IP address field of the message.
When an IGMPv2 device receives a general query message, the device compares the source IP address in the message with its own interface address. The device with the lowest IP address on the subnet is elected the IGMP querier.
All devices (excluding the querier) start the query timer, which is reset whenever a general query message is received from the IGMP querier. If the query timer expires, it is assumed that the IGMP querier has gone down, and the election process is performed again to elect a new IGMP querier.
C is incorrect.
I would rather say B and D
