Air is also the most important source for the other noble gases.T races of krypton are found in various minerals, the most important source of Krypton is Earth's atmosphere. Helium obtained from natural gas and radon is obtained as a byproduct during radioactive disintegration.
So Rn is obtained during radioactive disintegration not Kr.
So Krypton is obtained during radioactive disintegration is the wrong statement.

Explanation:
The correct statement is option 'C': Krypton is obtained during radioactive disintegration.
Explanation:
- Statement a: Helium has the lowest boiling point among the noble gases.
- This statement is correct. Helium has the lowest boiling point (-268.93°C) among all the noble gases. It is a colorless and odorless gas that remains in a gaseous state at room temperature and pressure.
- Statement b: Argon is used in electric bulbs.
- This statement is correct. Argon is commonly used in electric bulbs to maintain an inert atmosphere and prevent oxidation of the filament. It is an abundant noble gas and is chemically inert.
- Statement c: Krypton is obtained during radioactive disintegration.
- This statement is incorrect. Krypton is not obtained during radioactive disintegration. Krypton (Kr) is a noble gas that is chemically unreactive and does not undergo radioactive disintegration. It is obtained through the fractional distillation of liquid air.
- Statement d: Xe forms XeF6.
- This statement is correct. Xenon (Xe) can form compounds, and one of them is xenon hexafluoride (XeF6). XeF6 is a strong oxidizing agent and is used in chemical reactions and synthesis.
Therefore, the correct statement is option 'C': Krypton is obtained during radioactive disintegration. Krypton is not obtained through radioactive disintegration, but rather through fractional distillation of liquid air.
