Within Display & Video 360, what distinguishes blocklists from sensitive categories?

In Display & Video 360, blocklists are custom lists of URLs or apps that you create and manage to prevent your ads from showing on specific placements. You have full control over blocklists, allowing you to add or remove items as needed. Sensitive categories, on the other hand, are predefined classifications of content (e.g., "Tragedy & Conflict," "Sexually Suggestive Content") provided by ad exchanges and publishers. These categories are fixed and cannot be directly modified by advertisers. You can choose to exclude sensitive categories from your targeting, but you cannot edit the content within those categories. The other options are incorrect because the ability to modify is the key differentiator, not impression limits.
