Which statement about the Oracle Grid Infrastructure Home is correct?

Which statement about the Oracle Grid Infrastructure Home is correct?

A.
The directory path must be the same as an Oracle Home directory.

B.
The directory path can be different on different nodes.

C.
The directory cannot be created before you install your Oracle software.

D.
To create an Oracle Grid Infrastructure path, ensure that it is in a separate path, and not under
an existing Oracle base.

Explanation:
D: If you choose to create an Oracle grid infrastructure home manually, then do not
create the Oracle grid infrastructure home for a cluster under either the grid installation owner
Oracle base or the Oracle Database installation owner Oracle base. Creating an Oracle
Clusterware installation in an Oracle base directory will cause succeeding Oracle installations to
fail.

Requirements for Creating an Oracle Grid Infrastructure Home Directory

During installation, you are prompted to provide a path to a home directory to store Oracle grid
infrastructure software. Ensure that the directory path you provide meets the following
requirements:
* (not a) It should be created in a path outside existing Oracle homes, including Oracle
Clusterware homes.
* It should not be located in a user home directory.
* It should be created either as a subdirectory in a path where all files can be owned by root, or in
a unique path.
* (not C) If you create the path before installation, then it should be owned by the installation
owner of Oracle grid infrastructure (typically oracle for a single installation owner for all Oracle
software, or grid for role-based Oracle installation owners), and set to 775 permissions.
