On AIX systems， where DNS resolution takes precedence over NIS， a particular process needs to resolve names using /etc/hosts first.  Which of the following processes is the best way to accomplish this without affecting the rest of the system’s name resolution？（）

• A、Set the NSORDER environmental variable of the environment which invokes the process to：NSORDER="local，nis，bind"
• B、Set the NSORDER environmental variable of the environment which invokes the process to：  NSORDER="hosts=auth，nis，bind"
• C、Edit /etc/netsvc.conf to add a line similar to the following： process /full/path/of/process {hosts=local，nis，dns}
• D、Unset NSORDER environment variable of the environment which invokes the process
