Dereliction of duty occurs when an officer fails to deliver found property to the official custodian without undue __________.

The correct answer is "delay" because dereliction of duty specifically refers to an officer's failure to perform their responsibilities in a timely manner. When an officer finds property, they are obligated to turn it over to the official custodian promptly, ensuring that the chain of custody is maintained and that the property is recognized and processed according to legal and departmental protocols.

By emphasizing the need to avoid undue delay, the focus is on the urgency and importance of handling found property correctly. The term "delay" encapsulates the idea that an officer should not leave property unaccounted for or unnecessarily postpone the transfer, which could lead to complications or potential loss of evidence.

Other options like disturbance, notification, and disruption do not capture the essence of timely action required from officers. While they might speak to issues related to process or communication, the key aspect in this context is the promptness with which the found property must be delivered.
