Sra

oops, B was supposed to be se dicen

thanks

Actually, the correct answer is a. se despiden. The correct translation of the sentence "¿Por qué no se despiden tu hermana y tú?" is "Why don't you and your sister say goodbye?"

The reason for this is that the verb "despedir" means "to say goodbye" in Spanish. In the sentence, it's used reflexively as "se despiden" which means "say goodbye to yourselves." The subject of the sentence is "tu hermana y tú" (your sister and you), and the verb is "despiden" (say goodbye). The rest of the sentence, "Porque siempre nos peleamos" means "Because we always fight."

So, in this case, option a. se despiden is the correct answer because it matches the verb used in the sentence. Options b. se dien, c. se hablan, and d. se gradúan do not fit the context of the sentence.
