Passage: A store promotes merchandise in the following ways: at any time of the year, either with seasonal sales, with holiday sales, or both. Each promotion lasts for one month. In any month, if the store wants to clear a certain category of goods, it announces a seasonal sale; if there is a holiday in a certain month and there are still items left in the warehouse, it announces an intervening sale. However, there are no festivals in November and there are no items left in the warehouse this month.
Question: Which of the following statements can be logically deduced from the above?
A. A.If a month doesn't have a seasonal sale, there must be a holiday sale this month.
B. B.If the holiday sale doesn't go on, it must be in November.
C. C.If a seasonal sale occurs in a certain month, there must be remaining items in the warehouse for that month.
D. D.If there is a holiday in a month, but there are no items left in the warehouse, a holiday sale is declared.
