    The correct answer to the following question will be Option C (Data dictionary).

    Explanation:

    In this question, the option is missing. The option for the given question is given below:

    A) Database Management system

    B) Database

    C) Data dictionary

    D) Entity-relationship Diagram

    Data Dictionary:

    A data dictionary, as described in the IBM Computing Dictionary, is a "git repository of data information such as context, relationships with other records, origin, use, and structure." Oracle describes this as a set of metadata tables. It gives the definition of metadata which is nothing else data about data.

    Option A and Option B do not define metadata that's why this option is not fruitful. Option D is the entity-relationship diagram it gives the diagrammatic representation between the entity it does not defines metadata that's why this option is not fruitful.

    Hence Option C i. e "Data dictionary" is the correct answer.
