How to get the Audit vault version information from the Database or from SQLPLUS

Dear Experts,

 Please provide your thought on below question:

 One of my customers is asking how can he get the audit vault version information from the Database or from SQLPLUS. With following restriction:

 1.       He does not have OS privilege to access the AV server. So he can not run AVCTL show_av_status command.  He is connection from a remote client machine to the server.

 Please provide how he can fetch this information from Database. I already tried to see if V$OPTION, DBA_REGISTRY gives this info but no help from these two views.

IT is urgent. If it is not possible then also please let me know.
