The hybridizations of atomic orbitals of nitrogen in NO₂⁺, NO₃⁻ and NH₄⁺ respectively are

The hybridizations of atomic orbitals of nitrogen in $NO_2^+$, $NO_3^-$ and $NH_4^+$ respectively are
A sp, $sp^2$ and $sp^3$
B $sp^2$, sp and $sp^3$
C sp, $sp^3$ and $sp^2$
D $sp^2$, $sp^3$ and sp

Explanation

Linear, trigonal planar and tetrahedral.

Detailed Solution

$NO_2^+$ = sp (linear)
$NO_3^-$ = $sp^2$ (trigonal planar)
$NH_4^+$ = $sp^3$ (tetrahedral)
