Q36. The correct statements from the following are : (A) The decreasing order of atomic radii of group 13 elements is $\mathrm { Tl } > \mathrm { In } > \mathrm { Ga } > \mathrm { Al } > \mathrm { B }$. (B) Down the group 13 electronegativity decreases from top to bottom. (C) Al dissolves in dil. HCl and liberates $\mathrm { H } _ { 2 }$ but conc. $\mathrm { HNO } _ { 3 }$ renders Al passive by forming a protective oxide layer on the surface. (D) All elements of group 13 exhibits highly stable + 1 oxidation state. (E) Hybridisation of Al in $\left[ \mathrm { Al } \left( \mathrm { H } _ { 2 } \mathrm { O } \right) _ { 6 } \right] ^ { 3 + }$ ion is $\mathrm { sp } ^ { 3 } \mathrm {~d} ^ { 2 }$. Choose the correct answer from the options given below : (1) (A), (C) and (E) only (2) (A) and (C) only (3) (C) and (E) only (4) (A), (B), (C) and (E) only
