The shape of is
Square planar
Trigonal planar
T-shape
Tetrahedral
Over here, you can see there are so it means
bond pairs.
Steric Number
lone pair of
= steric number- no. of bonds formed
That means:- has :- 3 bond pairs & 2- lone pairs
Geometry= Trigonal bipyramidal
But it has 2 lone pairs of
geometry
shape
Shape is shape
Hence, option number (3) is correct.
