B Correct answer
Explanation

Helium has the lowest boiling point of all elements at approximately -268.93°C (4.22 K), just 4.2 degrees above absolute zero. This is due to its extremely weak interatomic forces as a noble gas. Hydrogen boils at -252.87°C, Neon at -246.08°C, and Argon at -185.8°C. Boron is a solid metalloid with a much higher boiling point of ~4000°C. Helium's unique properties make it essential for cryogenic applications.
