Given the following network configuration, how many subnets are there and what would be their feasible IPs respectively?

Question $4$ options:

Two subnets. LAN$1$: $10\mathrm{.}1\mathrm{.}1\mathrm{.}0/24.$ LAN$2$: $192\mathrm{.}168\mathrm{.}1\mathrm{.}0/24$

Three subnets. LAN$1$: $10\mathrm{.}1\mathrm{.}1\mathrm{.}0/24.$ Direct link between Router$0$ and Router$1$: $10\mathrm{.}0\mathrm{.}0\mathrm{.}0/30.$ LAN$2$: $192\mathrm{.}168\mathrm{.}1\mathrm{.}0/24$

Three subnets. LAN$1$: $10\mathrm{.}1\mathrm{.}1\mathrm{.}0/24.$ Direct link between Router$0$ and Router$1$: $10\mathrm{.}1\mathrm{.}1\mathrm{.}2/24.$ LAN$2$: $192\mathrm{.}168\mathrm{.}1\mathrm{.}0/24$
