Mr. Van Daan decide to sell Mrs. Van Daan's fur coat.

Explanation:

Mr. Van Daan asked Miep to sell his wife's fur coat because they did not have enough money to buy cigarettes. When Mrs. Van Daan found out, she got angry with her husband. That was her favorite coat, as Mrs. Van Daan got it from her father and it was really expensive. She wanted to sell the coat after the war is finished and buy some new clothes.
