You Buy Some Fresh Fruit at the Grocery Store

You buy some fresh fruit at the grocery store.When you get home,you are in a hurry,and you put the fresh fruit in the crisper with some overripe fruit.At the end of the week you are disappointed to find that your new fruit has already become overripe.What happened?

A) The refrigerator was probably set too high.As a result,the production of auxin was induced in overripe fruit and caused production of ethylene in the fresh fruit.
B) The fresh fruit was not washed before refrigerating,so ethylene was still present on the surface of the fruit,causing the fresh fruit to overripe.
C) The overripe fruit released ethylene that increased the rate of ripening in the fresh fruit.
D) The fresh fruit was damaged,producing ethylene that sped up the ripening process.
