Which of the following is most electronegative?

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 of the following elements has the maximum electronegativity?

Consider the following.
Statement-$I$ : The order of electronegativity of $B, Al, In, Tl$ is $B > Tl > Al > In$.
Statement-$II$ : Boric acid is a weak protonic acid.
The correct answer is

Fluorine is a better oxidising agent than $Br_{2}$. It is due to

Which of the following is the correct increasing order of electronegativity for the given elements?
