Correct Answer:
C
To print the elements of a string array separated by a specific string, the String.Join method is used in C#. This method takes two parameters: the first is the separator string and the second is the array to join into a single string.
Given the options and the requirement to separate array elements with a comma and a space (', '), the correct expression to use in a Log Message activity would be:
C . String.Join(', ', UserNames)
This will produce a single string with each element of the UserNames array separated by ', ' (a comma followed by a space).
