To connect EME (Enterprise Meta>Environment) to Abinitio Server, you would use the EME Datastore Settings.
Option A) Using ab_project_setup.ksh - This option is incorrect because "ab_project_setup.ksh" is a utility script used for setting up Abinitio projects, but it is not used for connecting EME to the Abinitio Server.
Option B) Using Run settings - This option is incorrect because "Run settings" are used to configure the execution settings for Abinitio graphs, but they are not used for connecting EME to the Abinitio Server.
Option C) Using EME Datastore Settings - This option is correct. EME Datastore Settings allow you to configure the connection details for the Abinitio Server within the EME environment.
Option D) None of the above - This option is incorrect because the correct answer is option C, using EME Datastore Settings.
Therefore, the correct answer is C) Using EME Datastore Settings.
