The electronegativity values of $F, Cl, Br,$ and $I$ are $4.0, 3.0, 2.8,$ and $2.5$ respectively. Which hydrogen halide has the highest percentage of ionic character?

Which one of the following has the highest electronegativity?

Keeping in view the periodic law and the periodic table,suggest which of the following elements should have the maximum electronegative character.

Given below are two statements :
Statement $I$ : The electronegativity of group $14$ elements from $Si$ to $Pb$ gradually decreases.
Statement $II$ : Group $14$ contains non-metallic,metallic,as well as metalloid elements.
In the light of the above statements,choose the most appropriate from the options given below :

In the third row of the periodic table,from $Na$ to $Cl$:

The relative order of electronegativity of $C$,$Ge$,and $Pb$ is
