Final answer:
The function signature (column_name, descending=True) is used to sort a column in descending order, where data is arranged from highest to lowest value.
Step-by-step explanation:
The function signature (column_name, descending=True) indicates that the function is intended to sort a column in descending order. When you call a function to sort data and you specify a column name with the parameter descending set to True, it will arrange the data in that column from highest to lowest value (in descending order). Therefore, the correct option in this context would be Option 2: Sort the column in descending order.
In the context of sorting data in a table, the function signature (column_name, descending=True) represents the option to sort the column in descending order. The 'descending=True' parameter indicates that the data in the column should be sorted from highest to lowest. If 'descending=False' or omitted, the data would be sorted in ascending order, from lowest to highest.
