(which of the following statements is the best description of the kinetic theory of matter)matter is made up of electrons, which are in constant motion and have energy. matter is made up of atoms, which are in constant motion and have energymatter is made up of atoms which seldom move and do not possess energymatter is made up of compounds, which are in constant motion and have energy

The correct option is B.
Matter is defined as anything that has mass and occupy space. The kinetic theory of matter states that all matters are made up of huge number of small particles which are in constant motion. These small particles are called atoms. Each atom has sub particles, which are electrons, protons and neutrons. The electrons are in constant motion orbiting the nucleus in which the protons and the neutrons are located. The electrons are able to move about constantly because they possess energy.
