Discontiguous network question

I just struck the following practice test question: "A network is referred to as discontiguous if it has been subnetted but the subnets are not physically accessible to each other via a router."
The correct answer is True, I answered False.
If you have three routers, A B and C all using subnets of the 10.0.0.0/8 network, even though the network is subnetted and the 10.1.0.0/16 subnet might be on the other side of router C (as opposed to a connected route) wouldn't the network still be contiguous?

It could actually be divided by any major network (or subnet of), doesn't necessarily have to be class A. -

But 192.168.1.0/26 and 192.168.1.64/26 and 192.168.1.128/26 would be contiguous.
