The preceding information shows the entry status of an IGMP interface on Ethernet 6/1/1 on a router.

Assume IGMP sends the group-and-source-specific Query message. Which of the following statements is true?

AIGMP sequentially sends two messages; The source carried in one of the messages is 20.1.1.56 with no S flag bit set; the source carried in the other message is 20.1.1.57, with the S flag bit set to1.

BIGMP sequentially sends two messages: The source carried in one of the messages is 20.1.1.56 with the S flag bit set to 1; the source carried in the other message is 20.1.1.57, with no S flag bit set.

CIGMP sends only one message carrying two sources 20.1.1.56 and 20.1.1.57, with the 5 flag bit set to1.

DIGMP sends only one message carrying two sources 20.1.1.56 and 20.1.1.57, with no S flag bit set.
