Question

The man, likely a superior, is assigning a difficult task. He uses the phrase 「いささか酷な気もする」 (isasaka koku na ki mo suru - 'I feel it's a bit harsh') to acknowledge the difficulty and show consideration. He is not, however, offering a way out. The appropriate professional response is to accept the challenge willingly. Option 1, 'Not at all, if you'll entrust it to me, I'll do my absolute best,' shows a positive and proactive attitude. Option 2 is too confrontational and agrees that the task is harsh. Option 3 sounds like an attempt to immediately avoid the work, which would make a poor impression.
