Code to Select Current Active Sheet

I have a workbook with three worksheets, each named differently (tblQuestionsDC, tblQuestionsRAC, tlbQuestionsATO).

I need to alter the following string, or a new one, to select whichever worksheet is currently active, may it be tblQuestionsDC, tblQuestionsRAC, or tlbQuestionsATO:

ActiveWorkbook.Worksheets("tblQuestionsDC").Sort.SortFields.Clear
