• B. Paired and extremely inactive
• C. Unpaired and extremely inactive
• D. Paired and extremely reactive

Answer 1

The correct option is A Unpaired and extremely reactive

• Free radicals are atoms or groups of atoms with an odd (unpaired) number of electrons and can be formed when oxygen interacts with certain molecules. Once formed, these radicals are highly reactive.

• Free radicals are unpaired and extremely active. They can start chain reactions.

So the correct answer is 'Unpaired and extremely reactive'.
