Explanation
the default project template configuration records available in the Template Config module are Project task, Project, and Project template. These records define the fields and values that are copied from the template to the project when a project is created from a template. The other options are incorrect because:
B: Project subtask: Project subtask is not a valid record in the Template Config module, as it is a child of the Project task record2.
D: Task: Task is not a valid record in the Template Config module, as it is a parent of the Project task record3.
