Solution

The correct option is A 1
Flourine can never be prepared from fluorides by chemical treatment. Fluorine is the most electronegative element. It has very high affinity for electron. Hence, it is very difficult to remove an electron from fluoride ion.
Thus, none of the oxidizing agents can extract electrons from fluoride ions to give flourine.
