Did You Know?
The correct answer is 'HAD BEEN WORKING'. This is PAST PERFECT CONTINUOUS tense. We use this tense to show the cause of a past state or action, emphasizing the duration. Structure: had been + verb-ing. Example: 'Her eyes were red because she had been crying.' The working caused the tiredness, and 'all day' emphasizes the long duration.
