Which survey link fits all four of these criteria: Unique to each participant, Relies on browser cookies, Allows taking the survey again and again, Can't send Reminder and Thank You messages?

The choice of Multiple Completes Link is accurate because it is specifically designed to allow participants to take a survey multiple times while maintaining the uniqueness of their responses. This type of link is tailored for situations where researchers want to gather repeated feedback from the same participant without limitations. Participants can take the survey as many times as needed, which is ideal for scenarios where responses may change over time or where repeated measures are necessary.

Additionally, the Multiple Completes Link does not rely on browser cookies, making it distinct from links that would restrict survey access based on previous completions. Since participants can repeatedly enter the survey, there is no mechanism to send Reminder and Thank You messages directed specifically at those who have completed the survey, as such links do not provide the researcher with identifiable participant data.

This set of features makes the Multiple Completes Link an excellent choice for dynamic data collection where participant responses need to be revisited and refreshed.
