D) Specifying a multicast source? Really? That's like asking me to remember my own birthday. Report message all the way!

Report message, hands down. It's the MVP of IGMP, the LeBron James of network protocols.

I'm going with C. Report message. It's the one that lets the router know 'Hey, I want in on this multicast party!'

Gotta be the Report message. It's the one that keeps the internet running, like the glue that holds the whole thing together.

Report message seems like the obvious choice here. I mean, who doesn't love a good report, am I right? *wink wink*
