Correct Answer: Helium
Solution : The correct option is Helium.
The cooling medium used for the Large Hadron Collider (LHC), superconducting magnets in MRI (Magnetic Resonance Imaging) scanners, and NMR (Nuclear Magnetic Resonance) spectrometers is typically liquid Helium (LHe). Liquid Helium is used to maintain the superconducting properties of the magnets, allowing them to operate at extremely low temperatures, and generate the strong magnetic fields required for these applications.
