An advertiser creates a new ad group in a campaign that is set to run on all relevant sites across the Google Display. If both keywords and placements are added to the ad group, they would work together to:
A. Determine where on the Google Display Network the ads will run
B. Impact search results and cost-per-click (CPC) on the Google Display Network
C. Determine the target return on investment (ROI) for a given ad group
D. Impact the time of ads that the impacts are eligible to show
