💡 Detailed Explanation
The correct answer is Option 1: 'Yes, I studied very hard, so I will do my best!' The question asks about the likelihood of passing tomorrow's test ('合格できそうですか'). Option 1 gives an enthusiastic response indicating preparation. Option 2 contradicts the premise by saying the test ended yesterday ('昨日終わりました'). Option 3 is a congratulatory response.
