Which of the following statements about atomic spectra is/are correct?
i.The discrete line spectrum of elements is evidence that electron energies are quantized
ii.Lines in the spectrum are discrete because electron energies are restricted to certain values
iii.Energy is emitted from atoms as electrons move from higher energy levels to lower energy levels
iv.Electron transitions of differing energies produce different wavelengths of light.
A)i and ii
B)i and iii
C)ii and iv
D)i, iii, and iv
E)All are correct statements.

All of the statements are correct. The discrete line spectrum occurs because electrons are restricted to specific energy levels (i and ii). When electrons move from higher energy levels to lower ones, they release energy in the form of light, and the different energies of these transitions produce different wavelengths in the spectrum (iii and iv).
