Evaluating Impact of Bidding Strategies on Ad Delivery

Consider two campaigns: one uses Manual CPC bidding, and the other uses Enhanced CPC (ECPC) bidding. Which statement correctly compares their bidding behavior?

A Manual CPC lets you set fixed bids, while ECPC adjusts bids in real-time to increase conversions without exceeding your max CPC.

B Both Manual CPC and ECPC always bid the same amount for every click.

C ECPC bidding ignores your max CPC and bids as high as possible to get clicks.

D Manual CPC automatically increases bids for conversions, but ECPC requires manual adjustments.

Manual CPC lets advertisers set bids manually. ECPC adjusts bids up or down in real-time to try to get more conversions while respecting max CPC limits.
