Let's say computers A, B, and C are all connected to a hub.

If really a hub and not a switch, which is far more common today, even
when called a hub.

Let's say computer A sends a packet to computer B.

Does computer C's Ethernet card discard the packet or does
computer C's CPU discard the packet?

Either can happen, depending on the details of the card, the OS, and
any drivers thereof.

Can a packet sniffer on computer C see the packet?

If a hub (see above) and with the right drivers, then yes.
