      You risk spraying in the dark

    Correct Answer
    B. You risk bract development.
    Explanation
    Spraying PGR's after the beginning of short days can risk bract development. Bracts are modified leaves that surround and protect the reproductive structures of certain plants, such as flowers. They are responsible for attracting pollinators and providing support to the flowers. If PGR's are sprayed during this time, it can disrupt the natural development of bracts and affect their functionality. This can result in improper pollination and reduced flower quality. Therefore, it is advisable to avoid spraying PGR's after the beginning of short days to prevent any negative impact on bract development.
