The list of individual responses list does not seem to give reference to the actual tracking link they have used to submit responses.
How do I find out the tracking link used by each individual respondent?

If you open an individual response, the link used to enter the response will be listed under the DETAILS tab.
A better approach might be to export the response data as a CSV file. This will let you review the data, including the link used, much easier than looking at individual responses.
