Which of the following represents the standard format of a Digital Object Identifier (DOI) used to uniquely identify academic publications?

### Why this is right The supplied publication information gives the digital object identifier (DOI) as `10.1080/01490409809512269`. The date and shortened or altered number are not the identifier shown on the page. ### The concept A digital object identifier is a persistent identifier used to identify a digital publication. It is different from a publication date, upload date, citation count, or readership count. ### The other options - **10.1080/01490409809512296**: This changes the final digits and is not the identifier shown. - **14 November 2015**: This is the stated upload date, not an identifier. - **014904098**: This is only part of the identifier shown and omits its full form. ### Terms - **DOI**: Digital Object Identifier, a persistent identifier for a digital object such as a scholarly article. ### Remember Copy an identifier exactly; a changed digit can point to a different record.
