destination host unreachable  = this means the next hop or end device do not know how to reach the destination.

traceroute helps you, where it stops, that is the device you need to investigate the routing.

Rather instruction manual,. you need to provide the configuration you have done on your lab

post below information from all devices :

show run

show IP route

show IP interface brief
