Hi Shanky,
That’s my understanding as well, ip igmp join-group the router will process and respond to ICMP request to the group and when you configure using ip igmp static-group the router won’t process it and will pass directly the requests to the source of the multicast group using fast switch process.
So since the question advises you to configure and not allow SW1 to process switch the traffic and also says that that the application he is using will not be generating IGMP join messages so for testing purposes I think the only way is to configure for the router to respond to ICMP requests is using “ip igmp join-group” but the solution says otherwise.
