Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : At constant temperature and pressure, equal volumes of all gases contain the same number of molecules. Reason (R) : At constant temperature, the mean molecular energies of these gases will be equal. In the light of the above statements, choose the most appropriate answer from the options given below :

Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : The zero point energy is $\frac{1}{2}h\theta$, it is the lowest value of the energy of the Harmonic Oscillator. Reason (R) : Harmonic Oscillator is in equilibrium with its surroundings, it is called zero-point as it corresponds to an energy $E=E_0$ and not to $E=0$ when the external temperature approaches to $0 \text{ K}$. In the light of the above statements, choose the most appropriate answer from the options given below :

Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : The wavelength of radiation is displaced as temperature changes, but the product of wavelength and temperature remains constant. Reason (R) : Wien's Law is a special case of Planck's radiation law in the region of longer wavelength.
