igmp querier , assert winner and DR confusion on election

hi group ,

R1 , R2 , R3 are connected on a multiaccess segment sharing ip address from
10.1.123.X /24 subnet where X is the router no .

now when it comes to cost R2 is having lowest cost to reach the SOURCE .

All the router has equal cost to Rp. igmp ver is 2

question :

1) who will be elected as assert forwarder ? DR ? Igmp Querier ?

1) I believe all three roles are seprate or is there any overlap of roles?

i have read some where that igmp querier is the one who forwards the
traffic on LAN but in my case R2 should be
the Mcast data forwarder .

Regards
