Option 3 is the right answer.
I have two cats named Whiskers and Jack. Whiskers is shy and quiet, but(1) Jack is busy and noisy most of the time. Even though(2) they have different personalities, Whiskers and Jack like each other. Jack will curl up with Whiskers for a nap after running around all morning. Likewise(3), Whiskers will wrestle with Jack when he needs a playmate. If Jack becomes too rough, Whiskers hisses to warn him that he needs to settle down. Nonetheless(4), they're best friends.
