The answer is B ( conozco)
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

"Eres" already implies the person it's talking to (you, in this case), if we wanted to make it formal, we would've used "Usted es" (You (formal) are)
