Answer:
D) Bose-Einstein condensation is the correct answer.
Explanation:
When temperatures are near absolute zero, Bose-Einstein condensation causes atoms to begin to clump.
Bose-Einstein condensate where atoms in the group or separate atoms are cooled to a temperature that is very near to the absolute zero.
When the group of atoms reached that temperature close to absolute zero, then atom has no free energy left and they are not in the moving stage. At that stage, the atoms start to clump together and they enter into the same energy level.They become similar, in terms of physical appearances.
