(A) The electronegativity values for group $13$ elements are: $B (2.04)$,$Al (1.61)$,$Ga (1.81)$,$In (1.78)$,and $Tl (1.62)$.Comparing these values,the order is $B > Ga > In > Tl > Al$.However,considering the general trend and the specific values provided in standard textbooks,the electronegativity decreases from $B$ to $Al$,then increases slightly due to poor shielding of $d$ and $f$ electrons in $Ga$,$In$,and $Tl$.The correct order is $B > Ga > In > Tl > Al$.

The correct order of electronegativity of group $13$ elements is
