The answer is option D "electron-cloud model." A electron-cloud model includes: includes positive charge, contains electrons, explains the photoelectric effect, suggests the probable location of electrons. It was also invented by Erwin Schrödinger.
Dalton model said that atom is indivisible. Thompson’s model gave the plum and pudding model where the electrons are embedded like plums in a pudding of positive charge. Bohr’s atomic model proposed that electrons moved in definite orbits around the nucleus in an atom. Schrondinger's electron-cloud model proposed that electrons are not definite particle but they exists as diffused cloud. The position of electron cannot be stated exactly but the probability of finding an electron in a 3 dimensional space can be given.
