Step 1: Understanding the Task
The task is to find the correct question tag for the statement.
Step 2: Applying the Rules of Question Tags
We use the positive-negative flip rule.
Step 3: Detailed Explanation
The main statement is "Shreya hasn't passed the exam...". The word "hasn't" (has not) makes the statement negative.
Therefore, the question tag must be positive.
The auxiliary verb is "has". The positive form is "has".
The subject is "Shreya," which is a female name. The corresponding pronoun is "she".
Combining the positive auxiliary verb and the pronoun gives the tag: "has she?".
Step 4: Final Answer
The negative statement requires a positive tag. The correct tag is "Has she?". Therefore, option (A) is the correct answer.
