    need to place each visualization in a separate layout container and then add a showhide button for
    each container. You can customize the appearance and behavior of the buttons to suit your needs.

    Correct Answer: C

    Explanation

    The central region has the smallest distribution of profits because it has the smallest interquartile\
    range (IQR), which is the distance between the first and third quartiles of the box plot. The IQR
    measures the spread of the middle 50% of the data. The smaller the IQR, the less variation in the
    data. Reference: https://help.tableau.com/current/pro/desktop/en-us/buildexamples_boxplot.htm
