What level or levels can ad targets be set?

The selected answer options are correct because ad targets can be set at both the Campaign level and the Ad group level. At the Campaign level, advertisers can apply broad targeting settings that apply to all the ads within that campaign, such as location, language, and device targeting. These settings provide overarching control over the direction and audience of the campaign as a whole. At the Ad group level, targeting can be further refined, allowing advertisers to set more specific targeting criteria for individual ad groups within the campaign. This allows for more granular control, such as targeting different keywords or audiences within different ad groups, providing flexibility to optimize for different segments. The Account level is not typically used for direct ad targeting, and while Keyword level targeting is important for matching ads to search queries, it is not the same as setting ad targets. Therefore, the most precise and customizable options are at the campaign and ad group levels.
