D Correct answer
Explanation

The find command with '-mtime +30' finds files modified more than 30 days ago. The '-exec' flag allows executing a command on each found file, and 'ls -lrt' lists them with details. The escaped semicolon '\;' terminates the -exec command. Option A incorrectly includes '/tmp/user' in the command. Options B and C use non-existent flags (-mmonth, -mday).
