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?
A.These are alternatives to hydro-fluorocarbon refrigerants
B.These are explosives in military weapons
C.These are high-energy fuels for cruise missiles
D.These are fuels for rocket propulsion
Explanation: * (b) These are explosives in military weapons is correct: CL-20, HMX, and LLM-105 are high-energy explosive materials primarily used in military and defense applications. * CL-20 is one of the most powerful non-nuclear explosives known, but is highly sensitive to shock. * HMX (Octogen) is a widely used nitramine explosive used in military-grade plastic explosives and shaped charges. * LLM-105 is classified as an "insensitive high explosive" designed to enhance transport safety without losing significant explosive power.
