It is present with a $90^\circ$ clockwise rotation. The 'L' shape and the extending horizontal line segment match perfectly. This is the correct option.\nOption (B) ![Diagram Required](): This option does not contain Figure A in any orientation. The structural elements of Figure A are not present.\nOption (C) ![Diagram Required](): This option does not contain Figure A in any orientation. The specific combination of lines forming Figure A is absent.\nOption (D) ![Diagram Required](): This option does not contain Figure A in any orientation.
