What will be the result of the following configuration？（）   Log_archive_dest_1=location=c：/oracle/arch/mydb Log_archive_dest_2=location=z：/oracle/arch/mydb
A

 An error will occur during database startup because the second parameter is not valid.

B

 An error will occur during database startup since you are trying to create archived redo logs in two different locations.

C

 Archived redo logs will be created in two different locations by the ARCH process.

D

 Archived redo logs will be created in two different locations by the LGWR process.

E

 Neither parameter setting is valid， so the database will not start up.
