    Solution

    The correct answer is B , as metadata refers to "data about data." A database schema is a prime example of metadata, providing details about table structures, column data types, relationships, and constraints. Option A : A row of data is actual data, not metadata. Option C : Dashboards represent analyzed data, not metadata. Option D : Reports summarize data, while metadata describes it. Option E : An image file is data, not metadata.
