Which is most likely an example of an angular molecule?

An angular molecule has a bent shape, with atoms arranged at an angle around the central atom. In H₂O, oxygen has two bonding pairs and two lone pairs; the lone pairs push the O–H bonds together, creating a bent shape. NH₃ is trigonal pyramidal, SiCl₄ is tetrahedral, and H₂CO is trigonal planar around carbon.
