Refer to the exhibit.

A static-route command follows the structure ip route destination-network subnet-mask next-hop administrative-distance. The required destination is 192.168.10.0/24, which corresponds to subnet mask 255.255.255.0. The next-hop address must be 192.168.20.1, and the routing-table exhibit confirms that the 192.168.20.0/24 network is directly connected through VLAN 10. The final value must be 2 because the question explicitly requires an administrative distance of 2. Option A uses the correct destination and next hop but sets the distance to 1. Options B and D incorrectly reverse the destination and next-hop networks. Consequently, only option C contains all four required elements and installs the route through the connected 192.168.20.0/24 network with the specified preference.
