I think it’s number 3 not sure tho
1) Le diste a José ese anillo de allí.
2) Le escribimos algunas veces.
3) Te compre este collar.
4) Nos han comprado mamá y papá estos souvenirs en Barcelona.
I am not completely sure about #4 I don’t think there is a word in Spanish for souvenirs but that might be only in my country.
It should be "esos" because 1. "Otros"and "blancos" are masculine. (Match subject's gender) 2. Here is a trick: "this" and "these" have "t"s (esto, esta, estos, estas); "that" and "those" don't (eso, esa, esos, esas). 3. "Zapatos" is plural, so match the subject's number. 4. Remember to always match the subject's gender and number. Hope that helps!
