I belive the answer would be,
A. Poner la mesa
Which means, "set the table".
The rest of the answer choices do not make sense.
"Fregar los platos," means, "wash the dishes".
"Invitar a los amigos," means, "invite friends".
"Caminar con el perro," means, "walk with the dog".
Hope this helps! Have a good day/night! c:
Wrong subject, lol. But I would infer that the rates of evaporation is higher since the more evaporation there is then the more substances are left behind by the ocean water. (In other words, salt)
