Correct Answer: AC
The command output indicates that node protection tunnels are established at R2 (10.10.10.2) and R1 (10.10.10.1), shown by the '@ n' symbol next to their IP addresses. This indicates that node protection is in place, rather than simple link protection, which would only be indicated by the '@' symbol without an 'n'. This eliminates the options of link protection tunnels at R4 and R6. Additionally, R1 has established a node protection tunnel, making the statement that R1 has not established one incorrect. Therefore, the correct answer is that R2 has established a node protection tunnel.
