Exp) Option b is the correct answer.

The substances CL-20, HMX, and LLM-105 are all part of a class of chemicals known as high-energy explosives. These are powerful explosive compounds developed for military applications, particularly in warheads, bombs, and other precision munitions.

Overview of Each Compound:

• CL-20(Hexanitrohexaazaisowurtzitane): Developed in the 1980s at the U.S. Naval Air Weapons Station China Lake, CL-20 is among the most powerful non-nuclear explosives known. It offers superior performance compared to traditional explosives like HMX and RDX, with higher detonation velocity and energy density.
• HMX: An acronym for “High Melting explosive,” HMX is a widely used and powerful nitroamine high explosive, chemically related to RDX. It has been used for decades in various military applications
• LLM-105 : Synthesized in the 1990s at Lawrence Livermore National Laboratory, LLM-105 is an insensitive high explosive. It is designed to withstand high temperatures and mechanical shocks, making it suitable for use in munitions where safety and stability are paramount
