  Based on the configuration, channels 239.1.1.1, 239.1.1.2, 239.1.1.3 and 239.1.1.5 have already been established. What happens when this router receives an IGMP report to join group 239.1.1.6?

  A. The router tears down channel 239.1.1.3 first, and then establishes a new channel for 239.1.1.6.
  B. The router tears down either channel 239.1.1.1 or 239.1.1.2 first, and then establishes a new channel for 239.1.1.6.
  C. No existing channel is torn down, and the new channel for 239.1.1.6 is established as there are enough resources.
  D. The new channel 239.1.1.6 cannot be established, and a log is generated.
  D. The new channel 239.1.1.6 cannot be established, and a log is generated.
