• You’d use Page type.
• You’d use Purchase.
• You’d use Homepage name.
• You’d use Page path and screen class.

The correct answer is: You’d use Page path and screen class.

Explanation: When constructing a purchase funnel within Explore, you would utilize the “Page path” or “Screen class” dimension to specifically select a homepage view. These dimensions allow you to filter your data based on the specific pages or screens visited by users, enabling you to identify the entry point of the funnel and track user behavior as they progress towards a purchase.
