Google Ads auction-time bidding is different from Search Ads 360 intraday bidding in which of the following ways?

Google Ads auction-time bidding, leveraging Smart Bidding strategies, optimizes bids in real time for each individual auction based on numerous contextual signals. This allows for highly precise bid adjustments at the moment of the auction. In contrast, Search Ads 360 intraday bidding, while more frequent than daily bidding, adjusts bids several times throughout the day, not in real time for every single auction. It uses a different methodology to optimize bids based on performance trends observed over periods within a day. The other options are incorrect because Google Ads auction-time bidding does not set up portfolio bid strategies across multiple engines (that's a Search Ads 360 feature), and Search Ads 360 intraday bidding does not override device, location, and bid adjustments but rather works with them.
