Answer

C

Explanation

Fluorine being a non-metal and smaller in size, has the highest electronegativity. Chlorine has the highest electron affinity instead of fluorine due to interelectronic repulsions between the added electron and the other electrons in the electron cloud of small sized F atom. Caesium has highest electropositivity as it is an alkali metal having large atomic size and high metallic character. Ruthenium being a transition element shows highest oxidation number.
