If all three computers A, C and D are on the the same subnet (ie
192.168.1.0) and with the same subnet mask (ie 255.255.255.0), then
computers A and C should have the same default gateway. Which should be
the IP Address of the NIC directly attached to the same 192.168.1.0
network. With IP Forwarding turned on for computer D, it's default
gateway (route) should be set, on the second NIC, to the nearest
upstream router.
