Answer #1

If a molecule have identical (same) surrounding atoms and there is no lone pairs on central atom then molecular shape of the molecule determined by hybridization.

SP-hybridization- linear

SP2 hybridization- trigonal planar

SP3 hybridization - tetrahedral

molecule with molecular formula AB3 has sp2 hybridization. so, molecular shape will be trigonal planar.

option 4th will be correct.
