start pining PC to its default router as it is a gateway router to reach remote LANs. IP of LAN are not configured on routers; u should use router's Gig interfaces instead of switchport F0/0/0; if u use those fa0/0/0/ switchport interface then u must use interface vlan x , aka SVI and add IP 172.16.20.1 there; then, u must remove some static routing - if not all static routes- and add no auto-summary - just in case ; make sure RIP runs version 2 under router RIP. check ip routing table then.
fixed those and let us know if u can ping local router first.

that is OK; that is how RIP works; classful way based on class A,B,C default mask; it is old protocol and upgraded from version 1; any subnetted networks will show up as their default class.
Add no auto-summary on all routers; u may wanna check static routes; I think they are no needed ; definitely not needed on Router0 ; Use and check destination using show ip route 172.16.23.3 - it shows static but should be directly connected on R0 as it is such.
Remove all static routes ; then if pings fail; check if u need to add a route - but i do not think so.

Ok Thanks, I did the RIP routing config because is a college's homework, and my teacher asked me to. One last thing, I'm having an error Request timed out when I ping 172.16.20.1 from the subnetwork C. Maybe you see anything wrong with the routers config?

Hello,
post your (zipped) updated Packet Tracer project (.pkt) file...

in this case, u must remove RIP from all routers and add static routes via CLI; Note that GUI router config tab is only PT thing; it does not exists (although some routers come with web-based configuration ability);
Static routing works only when all routers know how to reach remote network (lots of routes); Routers know about their directly connected networks only without any help (show ip route connected); then u must tell each router how to other networks ; aka network he does not know; each router needs static route to reach LAN network off remote router; Router0 knows about Subnet C and PC6 and Router1 knows its own sunbet A PC2; to get from PC2 to PC6 u must go via router1 and router0. So, on R1 u need to tell it (using ip route command ) to get to C and PC6 u must use R0 and vice versa; on R0 u need static route telling R0 to reach A off R1 u need to go to R1 via serial interface x.
command is ip route x.x.x.x m.m.m.m next-hop IP (or my exit interface);
