Read the exhausted college student's thought and choose the best option to complete it.

I have a mountain of laundry to do. I wish I ___ a magical robot to fold my clothes!

The correct answer is had.

To talk about a desire for a present situation to be different (an unreal present), we use "wish" followed by the past simple tense. Even though the student wants the robot now, the grammar requires the past tense form "had."
