Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Fluorine is the most oxidising agent and it is also most electronegative element.
Oxidising capability of a substance depends upon three factors:bond dissociation enthalpy, hydration energy and electron affinity.
Electron affinity of fluorine is less than that of chlorine but bond dissociation energy of fluorine is less than that of chlorine and its hydration enthalpy is also high due to its small size.
So fluorine is strong oxidising agent.
Both statements are true but reason is not correct explanation for the assertion.
