Choose the correct statement (s)
(i) The energy of an electron in an atom is always negative, because it is negatively charged.
(ii) The charge of an electron in an atom is positive
(iii) When an electron is at an infinite distance from the nucleus so that there is no electrical interaction , then orbitarily the energy of electron is taken to be zero
(iv) As the electron moves closer to the nucleus, energy is released and so its energy becomes less than zero i.e., negative.

B. iii and iv are correct
C. ii is correct
D. No statement is correct
