11 I ..... since this morning. I'm really hungry.

Analysis:

The sentence indicates a state that started in the morning and continues to the present, resulting in hunger. This implies a lack of eating during that period. 'Haven't eaten' (present perfect) fits this context as it describes an action (or lack thereof) that has relevance to the present situation (hunger).

Breakdown:

• A haven't eaten: Correct. Present perfect, indicating an action that has not happened up to the present time.
• B didn't eat: Incorrect. Past simple, refers to a specific completed action in the past.
• C haven't been eating: Incorrect. Present perfect continuous, emphasizes the duration of the action, which is less common for 'not eating' in this context compared to 'haven't eaten'.
