This question is quite difficult
Answer: d. None of the above is false.
Explanation: The reasons are:
Intermolecular forces should be reduced when molecules need to be vaporized, otherwise they will not be converted into vapours.
When the temperature increases, forces of attraction decreases which allows molecules to evaporate because energy will be increased which allows molecule to break bonding between them. Hence increasing temperature has effect on vaporization.
Dispersion forces is the weakest force between molecules and hydrogen bond is strong so molecule having only dispersion force will evaporate at the higher rate.
The endosymbiotic theory states that eukaryotic cells might have evolved from prokaryotic cells through a close realtionship.
Answer:
The answer is C.
