Comments

to be more specific and simple , we know that subnet don't have MAC address but routers and Hosts have so here definitely op[tion A and D are false .

Answer 2

Just remember not including switch anywhere.
Source IP will always be of H1 and destination IP of H3
t1: Source Mac of H1 , Destination mac of R1.1
t2: Source Mac of H1 , Destination mac of R1.1
t3: Source Mac of R1.2 , Destination mac of R2.1
t4: Source Mac of R2.2 , Destination mac of H3
t4: Source Mac of R2.2 , Destination mac of H3
