Scott (39) and Marlene (40) are married, and both are the parents of Seth (9). They all lived together until Marlene moved out on October 1. Seth stayed in the home with Scott. Marlene earned $42,000 during the year, and Scott earned $33,000. Scott and Marlene file separate returns. All are U.S. citizens, and all of Seth's support is provided by both of his parents. If each one tries to claim Seth as a dependent, who is entitled to do so?

Scott.

Marlene.

Neither, since they each have to file married filing separately (MFS).
