What is the common characteristic of the chemical substances generally known as CL-20, HMX and LLM-105, which are sometimes talked about in media? [Disease]

The correct option is These are explosives in military weapons.

Explanation:
CL-20, HMX, and LLM-105 are all high-performance, high-density chemical compounds developed and utilized as energetic materials. Specifically, they serve as powerful explosives and propellants in military applications:

1. CL-20 (Hexanitrohexaazaisowurtzitane) is a polycyclic nitramine explosive. It is considered one of the most powerful non-nuclear explosives in existence, offering higher performance and detonation velocity compared to older explosives.
2. HMX (High Melting Explosive / Cyclotetramethylene-tetranitramine) is a well-known nitramine high explosive widely used in military warheads, booster charges, and high-performance rocket propellants.
3. LLM-105 (2,6-diamino-3,5-dinitropyrazine-1-oxide) is an insensitive high explosive (IHE) designed to combine high performance with excellent thermal stability and low sensitivity to accidental detonation.

Therefore, the common characteristic of these three chemical substances is that they are explosives used in military weapons.
