Solution
The correct option is B Temperature and pressure Molecular arrangement of a substance depends on the temperature and pressure. Because state of matter depends on two things:
a) Average kinetic energy which is dependent on temperature.
b) Strength of intermolecular forces between the particles, which is dependent of pressure.
