Answer is D.

Among the given options, the products of equation A, B and C are aqueous solutions. Those are indicated by using (aq).

The balanced equation for the reaction between Li₂CO₃(aq) and FeCl₂(aq) is Li₂CO₃(aq) + FeCl₂(aq) → 2LiCl(aq) + FeCO₃(s)

LiCl is a salt while FeCO₃ is a Grey/green color precipitate. Hence, option D represents a precipitation reaction.
