• D. Food and beverage packaging materials.

Answer: (A)

MPPEH covers the items that are energetic or hazardous in naval operations. The main categories included are munitions, propellants, pyrotechnics, explosives, and related hazardous items. Munitions encompass ammunition and warheads; propellants are the chemical fuels used to propel projectiles; pyrotechnics include signaling devices, flares, and incendiaries; explosives refer to primary and secondary explosives used in ordnance; and related hazardous items cover components, packaging, and other associated materials that present handling or disposal hazards. This framing keeps the focus on materials that require special safety, storage, and disposal procedures due to their energetic or hazardous nature. Other options describe gear, electronics, or food-related materials, which are not the scope of MPPEH.
