Answer
D. Cesium (Cs)
Explanation
Electronegativity is the tendency of an atom to attract electrons. Among the given elements, cesium (Cs) is an alkali metal and has the lowest electronegativity due to its large atomic radius and low effective nuclear charge compared to nonmetals like fluorine, oxygen, and nitrogen.
