Answer:
Las
Explanation:
"Las" would make the most sense because the people Ernesto is referring to are all "sisters (hermanas)" aka all women
Whenever there is a group of women being pointed out, you have to use the feminine term for "them" which is "Las"
"Los" would work only if there was a male or males among them or only a group of males in general
"Lo" and "La" are singular but "hermanas" is more than one sister therefore those would be incorrect also
False because ir and ser are two different meanings.
Vivir is the verb meaning "to live."
a through c are different tenses of vivi. To live is not a command nor is there a formal/informal way to say it.
vivimos - We live
viven : They live
vive : She lives
