Substance A is a liquid or gas, while substance B is a solid.
Answer: C
Step-by-step explanation
The real world is made up of matters which can be classified into four types based on their condensed state. They are solid, liquid, gas and plasma.
Basically the matter is classified as solid, liquid and gases only.
Solid are the substance which have orderly arranged atoms and the most condensed state, the molecules vibrate very slowly in a solid molecule.
So this is matching with the properties given for Substance B.
The properties of other substance A is stated as less ordered and more vibrational frequency or we can say that molecules in substance A can travel faster than the molecules of substance B.
This can possible only when the substance A is either liquid or gas.
Because liquid or gas molecules have loosely arranged atoms compared to solid and they are the ones whose molecules can run faster compared to solid.
So substance A can be a gas or a liquid, while substance B is a solid.
