Decide if the following sentence is grammatically CORRECT or INCORRECT.Unter dem Auto liegt (your) dein Ball.

The sentence is correct. “Unter dem Auto” describes where the ball is, so “unter” takes the dative case here; “dem Auto” is the correct dative form. “Der Ball” is the subject of “liegt,” and “dein Ball” correctly uses the masculine nominative form of the possessive “dein.”
