Luke's Personal Information Theft

Explanation:

Dumpster diving is an act where personal information is stolen from discarded trash, leading to identity theft and fraud. When Luke's bank statement was taken from the trash and his personal information was stolen, this act is known as dumpster diving. Dumpster diving refers to the method where attackers search through someone's trash for discarded items that contain personal or sensitive information which can be used for identity theft or fraud.

The illegal use of this information, such as a social security number or bank account details, to impersonate someone and commit fraudulent activities like draining savings accounts or making large purchases is a significant consequence of dumpster diving. This is different from phishing, which involves tricking individuals into providing personal information via fraudulent emails or websites; shoulder surfing, which includes looking over someone's shoulder to obtain information; and spoofing, which is the act of disguising a communication from an unknown source as being from a known, trusted source.

The correct answer is option c) Dumpster diving.
