Which statement is true about the Oracle central inventory directory (oraInventory)?
A.
oraInventory must not be shared by all Oracle software installations on a single system.
B.
If ORACLE_BASE is set to /u01/app/oracle for the oracle user during an installation, OUI creates the
Oracle Inventory directory in the /u01/app/oracle/ oraInventory path.
C.
lf an OFA-compliant path is not created and the ORACLE_BASE environment variable is not set during an
Oracle Database installation, the Oracle Inventory directory is placed in the home directory of the user that
is performing the installation.
D.
Oracle software owners must be members of the same central oraInventory group, but they need not
have this group as their primary group.

D is not correct.
Ensure that this group is available as a primary group for all planned Oracle software installation owners.
It should be C.

If the primary group of an installation owner is the user home directory (for example, /home/oracle), then the Oracle Inventory is placed in the installation owner’s home directory. This placement can cause permission errors during subsequent installations with multiple Oracle software owners. For that reason, Oracle recommends that you do not accept this option, and instead use an OFA-compliant path.
If you set an Oracle base variable to a path such as /u01/app/grid or /u01/app/oracle, then the Oracle Inventory is defaulted to the path u01/app/oraInventory using correct permissions to allow all Oracle installation owners to write to this central inventory directory.
Agree since A, B, and D are incorrect.
