As we have learned

The energy (E) of a quantum of radiation -

$E=hv$

Where h is plank’s constant and $\nu$ is frequency

-

when the temprature is increased , black body emits high energy radiation  , from higher wavelength to lower wavelength

Option 1)

Photon has momentum as well as wavelength.

This is incorrect

Option 2)

Splitting of spectral lines in electrical field is called Stark effect.

This is incorrect

Option 3)

Rydberg constant has unit of energy

This is incorrect

Option 4)

Frequency of emitted radiation from a black body goes from a lower
wavelength to higher wavelength as the temperature increases.

This is correct
