(C) Electropositive character refers to the tendency of an element to lose electrons to form positive ions.In the periodic table,electropositive character increases down a group and decreases from left to right across a period.Comparing the elements: $K$ (Group $1$,Period $4$),$Ca$ (Group $2$,Period $4$),$C$ (Group $14$,Period $2$),and $Cl$ (Group $17$,Period $3$).$K$ is an alkali metal and has the lowest ionization energy among the given options,making it the most electropositive.The decreasing order of electropositive character is $K > Ca > C > Cl$.Therefore,the correct option is $(C)$.

Which one of the following is the most electropositive element?
