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
