您正在与一家全国性花卉经销商合作，为一个新的广告系列规划所需的广告素材。下面哪些步骤与广告素材的投放相关？

The correct answer includes "Creative rotation rules," "Creative aspect ratio," "Creative priority," and "Creative delivery time settings" because these are all direct configurations within Campaign Manager 360 that govern how and when an ad creative is displayed to users. Creative rotation rules determine the order or method of showing multiple creatives, aspect ratio is crucial for proper display across placements, priority influences which creative is served when multiple are eligible, and delivery time settings control the specific hours or days an ad runs. Incorrect options include elements like "Creative type" or "Creative weight" without other key delivery controls, or "Creative display duration" which is less about delivery configuration and more about the creative itself. While "Creative scheduling" is related, the correct answer provides more specific and comprehensive delivery-related settings.
