Which tag indicates that an item or component is unserviceable and condemned?

The correct answer is B, DD Form 1577, Unserviceable Condemned Tag, because this tag is specifically designated for items that have been determined to be unserviceable and are subsequently condemned, meaning they are no longer fit for use. The form serves a critical role in inventory management and accountability within military and defense operations, ensuring that items that cannot be repaired or reused are properly documented and removed from active stock.

This form helps maintain safety and efficiency by preventing the use of defective items that could pose risks to personnel or operations. By accurately marking and categorizing unserviceable condemned items, the military can streamline supply chain management and ensure that only serviceable equipment is available for use.
