Answer:
d. More ads in an ad group means more options for success in an auction.
Step-by-step explanation:
According not.Google when creating search Ad groups it is advisable to have 3 to 5 ads per group.
This is done because the more adverts that are included in a search the more the possibility of one of them meeting the needs of a person that is searching.
