💡 Detailed Explanation
The correct choice is Option 2: 'Because there is little overtime and he has more time for hobbies.' The man explains that his previous job paid well but had too much overtime. In his new job, there is almost no overtime ('残業がほとんどありません'), allowing him to enjoy his hobbies: '定時に帰れるので、趣味のスポーツをする時間が増えて、とても満足しています' (Since I can return at the regular time, my time to do sports has increased, and I'm very satisfied). Thus, Option 2 is correct.
