The correct identification of a primary high explosive is based on the sensitivity and the nature of the explosive materials. DDNP, which stands for Diazodinitrophenol, is known to be a primary high explosive because it is highly sensitive to heat, shock, and friction, making it capable of detonation under relatively low-energy conditions. Primary explosives are typically used to initiate secondary explosives and are characterized by their ability to explode with little external stimulus.

In contrast, TNT, PETN, and RDX are classified as secondary explosives. While they are still very powerful and can produce significant explosions, they require a primary explosive to detonate. Secondary explosives are less sensitive and generally need to be initiated by a shock wave from a primary explosive or by a detonator.

Understanding the distinction between primary and secondary explosives is essential in fields such as law enforcement and corrections, particularly for safety protocols and handling procedures.
