Question

Vosotras _______ traéis
Los
lo
os
las

Answer 1

it depends.. the phrase says you are bringing something but what is it? is it something plural or singular? is it an object or a person? masculine or femenine?

Answer 2

Well since it says vosotras it feminine..

Answer 3

yes I know, but vosotras is like 'you' in feminine, plural. I'll give you some examples:
-vosotras LOS traeis (some cups, for example) that LOS would be for 'LOS vasos' (the cups) so LOS would be 'the' in plural, masculine
-vosotras LO traeis (a cup) that LO would be for 'EL vaso' (the cup) so LO would be 'the' in singular, masculine
-vosotras OS traeis, in my opinion that is not possible because vosotras os traeis is like saying (you bring yourselves) and that doesn't make sense at all.
-vosotras LAS traeis is the same as LOS but in feminine, for example if you are going to say LAS BLUSAS which means the blouses
I hope this helped! If there's something you still don't understad, ask!

Answer 4

wait, I just realized I explained it wrong, I'll translate it for you:
-vosotras LOS traeis = you bring THEM (like you bring the cups) (that you/vosotras is plural and feminine) and that "THEM/LOS" is masculine
-vosotras LO traeis = you bring IT
-vosotras OS traeis = (you bring yourselves)
-vosotras LAS traeis = you bring THEM (this 'THEM/LAS' is feminine)
