Best answer
Correct option is (b) Fluorine

To elaborate: Accounting for only one missing electron, fluorine is highly reactive. Since it needs only one electron to complete its octet, it is the most electronegative element in the periodic table.  The decreasing order of electronegativity is F > Cl > O > N.
