    Correct Answer
    B. False
    Explanation
    The given statement is incorrect. MySQL is a popular relational database management system (RDBMS) that can indeed execute relational databases. It is designed to store, manage, and retrieve data based on the relational model, which organizes data into tables with rows and columns. MySQL supports various relational database features such as data integrity, data consistency, and the ability to establish relationships between tables through keys. Therefore, the correct answer is False.

    • D.

      All of the above

    Correct Answer
    A. One to One
    Explanation
    A one-to-one relationship in a relational database is an example of a relational database. In this type of relationship, each record in one table is associated with only one record in another table, and vice versa. This allows for efficient and organized storage and retrieval of data, as well as the ability to establish connections and dependencies between different sets of data.

    • D.

      None of the above

    Correct Answer
    C. All of the above
    Explanation
    All of the options listed (One to Many, Many to Many) are examples of relationships that can be represented in a relational database. In a One to Many relationship, one record in a table is related to multiple records in another table. In a Many to Many relationship, multiple records in one table are related to multiple records in another table. Both of these relationships can be effectively managed and represented in a relational database system. Therefore, the correct answer is "All of the above."
