The correct configuration for establishing an eBGP neighborship and advertising a network involves specifying the local AS number, the neighbor's IP address along with its AS number, and the network to be advertised with the correct subnet mask. Option C correctly configures Router A with its local AS number (65001), sets up Router B as a neighbor with its IP address (10.0.1.2) and remote AS number (65002), and advertises the connected network on interface G0/1 (10.0.1.0) with the appropriate subnet mask (255.255.255.0). This ensures that Router A will form an eBGP neighborship with Router B and advertise the connected network to it.
