Assertion :At low temperature, particles of matter occupy fixed position and exit in solid state. Reason: Under a given set of conditions of temperature and pressure, the state of substance depends upon the net effect of thermal energy and intermolecular forces.

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
At lower temperature, particles of matter have no energy as such. So, they occupy a fixed position and exist in a solid state.
As the temperature is increased, the molecules or particles of matter get thermal energy and starts vibration. This creates a distortion in a so-called ideal solid-state structure. The extent of vibration depends on the amount of temperature and pressure as well.
The increase of pressure will produce strain in the crystal. So, the state of the substance depends on the net effect of thermal energy and intermolecular forces at a given temperature and pressure.
