💡 Detailed Explanation
The correct choice is Option 3: 'Bring trash bags.' The woman suggests first putting unwanted items in bags and then vacuuming. The man responds, 'じゃあ、僕がごみ袋を持ってくるよ' (Okay, then I will bring the trash bags), and asks the woman to gather the unwanted items ('君は...いらないものを集めてくれる？'). Thus, the very first action the man takes is bringing the trash bags. Option 1 (vacuuming) and Option 2 (gathering unwanted items) are actions done later or by the woman.
