The substance that breaks easily or shatters is brittle. As malleable and ductile are hard in nature and volatiles are types of solute. Thus, option B is correct.
These substances are hard and rigid but contain little tensile strength that is they can be broken down into pieces easily on applying a little amount of pressure.
They have little deformation and poor capacity for conduction of current with high compressive strength and low tensile strength.
On applying pressure they fracture with little elastic deformation and some examples of it are some alloys with low plasticity, glass, and graphite. Their breaking is also known as brittle breakage.
Ductile are stiff and unable to break and the volatiles are type of solute easily dissolve in water malleable and are unbreakable or difficult to break. These all are the bad conductor of electricity.
Therefore, brittle is the substance among these which breaks. Thus, option B is correct.
