The correct answer is 'Introducing malformed or non-standard data structures' because it directly leads to data corruption by breaking the expected data format, which could render files unusable or inaccessible. 'Overloading the system with excessive traffic' would lead to Denial of Service (DoS) rather than direct data corruption. 'Implementing an ARP poisoning attack' could lead to a Man-in-the-Middle (MiTM) scenario but may not corrupt data on the filesystem itself. 'Exploiting weak service configuration' might escalate privileges or lead to unauthorized access but does not specifically aim to corrupt data.
