The correct answer is 'HAVE BEEN WATCHING'. This is PRESENT PERFECT CONTINUOUS tense. We use this tense for actions that started in the past and are still continuing now, emphasizing the duration. Structure: have/has been + verb-ing. Example: 'It has been raining all day' (and it's still raining). 'Since morning' indicates the action started in the past and continues to the present.
