In the LOOP AT ITAB INTO LINE construct, the work area LINE receives each row of the internal table during each iteration. After the loop completes, LINE contains the last record that was processed. This is standard ABAP behavior - the work area holds whatever value was last assigned to it. Option A is incorrect because LINE only temporarily holds one record at a time during iteration. Option B is incorrect because no error occurs. Option D is incorrect because LINE contains the last processed record, not nothing.
