Which of the following is a key aspect of the Data Protection Act?

The key aspect of the Data Protection Act that is highlighted in the correct response emphasizes the principle that personal data must be relevant and limited to what is necessary for the purposes for which it is processed. This principle ensures that organizations only collect and hold data that is needed for specific functions, thereby minimizing the amount of data that could potentially be mishandled or misused.
