In tandem ??

Over a lan each router will have all the needed arp entries. What is your worry ?

Tht's a is connected to b and b to c

By which media ?

UTP

ethernet - so A doesn't need C's ARP entry and viceversa, as they are on different subnets.

ok, what's the scenario if it is not UTP?

No difference - I asked to better understand.

Router's store arp only for its directly connected device.

A have ARP for B

B have ARP for both A & C

C have ARP for B
