You are developing the MyApp application that has a table, Table A.

Comprehensive and Detailed Explanation:

In ServiceNow application development, when you want specific records from a table to be included during the installation of an application on another instance, you must explicitly add those records to the application. This is achieved using the "Create Application Files" feature. By doing so, the selected records are packaged as part of the application, ensuring they are installed along with the application's components on any target instance.

Option A: The System Clone > Exclude Tables list pertains to instance cloning processes, not application installations. Modifying this list affects which tables are excluded during cloning but does not influence the inclusion of specific table records during application deployment.

Option B: While extending the Task table allows Table A to inherit certain functionalities, it does not automatically include its records during application installation. The inclusion of records is independent of the table's hierarchy.

Option C: Having an automatic number counter and setting the table property "Includes _data" to True is related to data management within the instance. However, this setting alone does not ensure that specific records are packaged with the application.

Therefore, to ensure that Table A's records are included during the installation of MyApp on another instance, you must add those records to the application using the "Create Application Files" feature.
