I don't know, this question seems a bit tricky. Maybe the answer is A? I thought the SSM multicast range was 232.0.0.0 to 232.255.255.255.

I agree with Karan, option B is definitely wrong. IGMP SSM Mapping does support IGMPv3 for SSM services.

I believe option B is incorrect because IGMP SSM Mapping does process reporting messages from IGMPv3.

Hmm, I was leaning towards D. If IGMP SSM Mapping isn't enabled, then IGMPv1 and IGMPv2 can't use the SSM services, right?

I'm pretty sure the answer is B. IGMP SSM Mapping doesn't process IGMPv3 reports, it's designed for IGMPv1 and IGMPv2 to access SSM networks.
