The correct statements from the following are:
(A) The decreasing order of atomic radii of group 13 elements is Tl > In > Ga > Al > B.
(B) Down the group 13 electronegativity decreases from top to bottom.
(C) Al dissolves in dil. HCl and liberates H2 but conc. HNO3 renders passive by forming a protective oxide layer on the surface.
(D) All elements of group 13 exhibits highly stable +1 oxidation state.
(E) Hybridization of Al in \(\left[\mathrm{Al}\left(\mathrm{H}_{2} \mathrm{O}_{6}\right)\right]^{3+}\)ion is sp3d2.
