Questions: La mamma e' in cucina, cosa sta facendo? Sta cucinando la cena! Sta parcheggiando l'auto! Sta andando al cinema! Sta prendendo l'autobus!

The answer is "Sta cucinando la cena!"

This option is the most logical because the context suggests that the mother is in the kitchen, which is typically where cooking activities take place.

This option is unlikely because parking a car does not usually happen in the kitchen.

This option is also unlikely because going to the cinema does not involve being in the kitchen.

This option is improbable as well because taking a bus does not occur in the kitchen.
