Which of the following describes the criteria for store visits conversion tracking?

The correct answer states that store visits conversion tracking requires sufficient data and privacy threshold compliance. This is accurate because Google uses aggregated, anonymized data and machine learning to estimate store visits, necessitating a large volume of ad impressions and clicks to ensure accuracy and protect user privacy. Without enough data, Google cannot confidently attribute visits to ads or meet its privacy standards. The other options are incorrect: Store visits tracking is not available for all business types (e.g., sensitive categories are excluded) and is limited to specific countries. It's not available in all countries and regions; availability is geographically restricted. It does have minimum impression and click requirements, as sufficient data is crucial for its functionality.
