What is a potential risk associated with dumpster diving?

The selection highlighting exposure of sensitive information as the correct answer addresses a critical risk linked to dumpster diving. When individuals engage in this practice, they often sift through discarded materials in search of valuables, documents, or other items. This can include sensitive personal information such as financial records, medical information, or identification documents. The exposure of such data can lead to identity theft, fraud, and other privacy violations, as the information can be misused by those who find it.

The other options do not align with the context of dumpster diving: increased awareness of personal data is more effective as a proactive measure rather than a risk, enhanced security measures would typically be a response to potential risks rather than a consequence of dumpster diving, and while the collection of physical evidence can occur in certain scenarios, it does not inherently represent a risk to the diver or to others as sensitive information would.
