What are two methods for renaming a field in a visualization?

Tableau allows a field to be renamed directly in the Data pane by making the field name editable or by selecting Rename from the field's contextual menu. Therefore, B and C are correct. For the first method, Tableau documentation specifies that the user can click a field name in the Data pane and hold the mouse button until the field name appears in an editable text box. The new name can then be entered and confirmed. Tableau also provides keyboard alternatives such as F2 or Ctrl+Enter. The second standard workflow is to open the field's contextual or drop-down menu and choose Rename. This changes the field name used within Tableau without changing the column name in the underlying data source. Replace References serves a different function. It substitutes one field for another throughout the workbook and is commonly used when replacing broken or obsolete field references; it is not simply a renaming command. Field Labels under formatting controls how field labels appear in a view rather than changing the Data pane field name. Tableau explicitly documents Data pane renaming and confirms that renamed fields retain the new Tableau-facing name within the workbook.
