Final answer:
The correct answer is a. malo (bad).
Step-by-step explanation:
The sentence "Me puede traer otro postre? Este está muy salado." translates to "Can you bring me another dessert? This one is very salty." In this sentence, "este" (this) refers to the dessert being discussed. The phrase "está muy salado" means "it is very salty." Since salty food is generally considered undesirable, we can conclude that the correct answer is a. malo (bad).
