In the context of a published research article, DOI stands for:

AData Object Integration

BDigital Object Identifier ✓ Correct

CData Object Interface

DDigital Object Interface

Correct answer: (B) Digital Object Identifier

Explanation

DOI stands for Digital Object Identifier, a permanent code assigned to a published document.

Data Object Integration names no recognised bibliographic identifier.

Data Object Interface confuses a naming scheme with a software connection.

Digital Object Interface again substitutes interface for identifier, which is incorrect.

A DOI resolves to the current web location of an article even if the URL changes.

DOIs are managed through registration agencies such as Crossref.
