A photon of wavelength 300nm interacts with a stationary hydrogen atom in ground state. During the interaction, whole energy of the photon is transferred to the electron of the atom. State which possibility is correct, (consider, Plank's constant `=4xx10^(-15)` eVs, velocity of light `=3xx10^(8)ms^(-1)` ionisation energy of hydrogen =13.6 eV)

A

Electron will be knocked out of the atom.

B

Electron will go to any excited state of the atom.

C

Electron will go only to first excited state of the atom.

D

Electron will keep orbitting in the ground state of atom.
