An advertiser wants to target users who abandoned items in their shopping cart with a small incentive to encourage them to complete their purchase. Which audience re targeting action combination should the advertiser use when setting up the conversion objective campaign?

The selected answer is correct because creating an "abandoned cart" audience requires isolating users who demonstrated high intent by adding an item to their cart but did not complete the final transaction. By including the AddToCart event, the advertiser captures the group of interested shoppers, while excluding the Checkout event ensures that the budget is not wasted on users who have already converted. This specific combination allows the advertiser to deliver a targeted incentive exclusively to the segment that dropped off at the final stage of the funnel, maximizing the efficiency of the conversion objective.
