A fashion advertiser on Pinterest wants to create an audience of people who have shown a high level of intent by saving and clicking on its Pins. Which type of engagement audience should be used?

The correct answer is "Optimized engagement action" because this audience type specifically targets users who have performed high-intent actions like saves and clicks on your Pins. This allows the advertiser to re-engage with users who have already demonstrated a strong interest in their content, making them more likely to convert. "Outbound clicks" is too narrow; while important, it doesn't encompass saves. "Actalike based on video views" is an audience expansion strategy, not a direct engagement audience, and focuses only on video views, not saves or clicks. "Comments and video views" is also too narrow, missing the crucial "saves" and "clicks" that indicate higher intent for a fashion advertiser.
