Explanation:

The question above is obtained from a story written by author Kristin Lewis. This story was about the admirable and brave thing a young polish girl who lived in Poland with her family did.

The name of the young girl was Stefania Podgórska. She helped to protect and save 13 people which included her friend Max Diamant and 12 other Jewish men, women and children in the basement of her house during the Holocaust.

During the period of the Holocaust, some Germans also referred to as the Nazis were rounding up Jews, arresting and killing them. Poland is a country that is close to Germany so these Germans also came to Poland looking for Jewish people.

Stefania Podgórska had a Jewish friend named Max Diamant. They were very close friends and she would visit his home were she would meet his parents and she would stay for a while. She was treated like a part of their family. From her continuous visitation of his place, she learnt Yiddish (language spoken by Jewish people) words from them.

Author Kristin Lewis writes that Stefania likely learned the meanings of several yiddish words from the diamants. Lewis writes this to support the idea that Stefania and the Diamants had a close relationship.

Therefore, option B is the correct option.
