Understand that the normal boiling point of a substance is the temperature at which its vapor pressure equals 1 atm (standard atmospheric pressure).
Recognize that neon is a noble gas with a very low boiling point, and its boiling point at 1 atm can be found in standard reference tables or phase diagrams.
Since the problem provides several temperature options, identify that the correct boiling point corresponds to the temperature where neon transitions from liquid to gas at 1 atm pressure.
Recall or look up the known normal boiling point of neon, which is approximately 27.1 K, indicating the temperature at which neon boils under 1 atm pressure.
Confirm that this temperature is consistent with the physical properties of neon and matches the given correct answer.
