The add method should simply add the Fruit object passed as a parameter to the ArrayList named fruits in the ShoppingCart class. Option B does this correctly by adding the object directly to the list. Option A unnecessarily creates a new object before adding it to the list. Option C and D use non-existent methods such as addItem instead of the correct add method for ArrayList.
