What is meant by “corporate author” in research?

The correct option is: A work produced by an institution, an association or a government agency

Explanation:
In academic research and citation systems (such as APA, MLA, or Chicago), a corporate author (also known as a group or organizational author) refers to a collective body that is responsible for the creation of a work, rather than any individual person.

Here is a detailed breakdown of the concept:
1. Collective Representation: Many publications—such as official reports, policy documents, code guidelines, or annual statistical reviews—are compiled by committees, departments, or entire organizations. Since no single individual claims personal authorship, the entity itself is designated as the author.
2. Common Examples: Typical corporate authors include international organizations (e.g., World Health Organization), professional associations (e.g., American Psychological Association), and government bodies (e.g., Department of Education).
3. Clarifying the Term: In this context, the word "corporate" does not exclusively refer to business corporations. Instead, it refers to any incorporated body, institution, association, or agency acting as a single cohesive unit to publish information.
