(C) You can set your own budget and can change it at any time.
(D) Machine models automatically determine your advertising budget
Explanation
Google Ads is the perfect choice for businesses who would like to reach more customers but have a limited budget because Google Ads allows you to set your own daily budget, individual ad budget and total campaign budget which you can change at any time.
If your campaign budget is reached then the ad campaign is paused and restarts automatically after you increase the budget. If the daily budget is reached then the ad is paused for the rest of that day and restarts automatically the next day.
