You work with a clothing brand that's launching a new parka collection. You want to see which winter sports publishers have space on their websites that's available for purchase. What Display & Video 360 module should you use to find that information?

In Google Display & Video 360, the Inventory module is used to discover and explore available ad placements, publishers, and deals where advertisers can buy advertising space. Since the clothing brand wants to identify winter sports publishers that have ad space available on their websites, the Inventory module is the appropriate place to search for and evaluate this inventory before purchasing it. The other modules serve different purposes: the Campaign module manages campaign structure, the Report module analyzes performance data, and the Creative module manages ad assets. Therefore, the correct answer is Inventory module, because it allows advertisers to find and evaluate publisher inventory available for purchase.
