What happens if you use the activity Insert Column with the Column Name property set to "Age" in an Excel table that already has this column?

• A. The column is updated
• B. New column is created
• C. An exception is thrown
• D. Data is overwritten

Answer: (C)

When the Insert Column activity is used with the Column Name property set to "Age" in an Excel table that already contains a column with the same name, an exception is thrown. This is due to the fact that the activity is designed to add a new column to the table, and it does not handle the scenario where a column with the specified name already exists. Instead of updating the existing column, the activity cannot proceed as intended, leading to an error or exception. In contrast, if the column name did not currently exist in the table, a new column would be successfully created, or if the data were to be updated or overwritten, that would represent different functionality not associated with the Insert Column activity. Thus, the occurrence of an exception effectively communicates that the action cannot be completed due to the naming conflict with an existing column.
