What criteria can be used when searching in Gmail?

The correct choice highlights useful criteria for effectively searching within Gmail. By selecting the sender, subject, content, and attachment, users can refine their searches to quickly locate specific emails based on various characteristics.

The sender allows users to filter emails from particular individuals or organizations, which is beneficial in both personal and professional communications. The subject helps users identify emails pertaining to specific topics, making it easier to find relevant information. Searching the content of emails is particularly powerful, as it enables users to locate messages based on keywords or phrases contained within the body of the email. Lastly, filtering by attachments allows users to find emails that include files, which is a common requirement when looking for documents or images sent via email.

While other options include relevant criteria, they may contain elements that are either too broad or not exclusively searchable in Gmail's interface, such as "admin settings" or "filters," which are not directly used to perform searches in user inboxes.
