Poppy petals function to attract pollinating insects. The pollination of a poppy flower triggers the release into that flower of a substance that causes its petals to wilt within one or two days. If the flower is not pollinated, the substance will not be released and the petals will remain fresh for a week or longer, as long as the plant can nourish them. Cutting an unpollinated poppy flower from the plant triggers the release into the flower of the same substance whose release is triggered by pollination. The statement above, if true, most strongly support which one of the following? ['Pollinating insects are not attracted to wilted poppy flowers.', 'Poppy plants are unable to draw nutrients from soil or water after the substance that causes wilting has been released.', 'The pollen on pollinated poppy flowers prevents their petals from absorbing the nutrients carried to them by their stems.', 'Even if cut poppies are given all necessary nutrients, their petals will tend to wilt within a few days.']
