The correct option is eDiscovery preservation hold.

eDiscovery preservation hold places a legal hold on mailboxes, SharePoint sites, OneDrive accounts, or on the results of a targeted search and prevents relevant content from being permanently deleted or altered while the hold is active. It is designed for litigation and compliance scenarios and it lets you preserve content for specific custodians or queries so only the targeted items are retained for the investigation.

Data loss prevention policies are focused on preventing sensitive data from leaving the organization and enforcing protection actions. They do not act as a legal hold and they do not guarantee that targeted content cannot be altered or removed for the purposes of litigation.

Retention labels and retention policies control how long content is kept and when it is deleted across mailboxes and sites, and they apply lifecycle rules organization wide or by location. They are not the same as a targeted legal preservation action and they lack the case and custodian controls provided by an eDiscovery preservation hold.

Organization retention settings set broad default retention behavior for a tenant and they are not designed to serve as targeted litigation holds. They are less precise and they do not provide the same legal hold management and preservation guarantees that eDiscovery holds provide.
