H2O.
Reason: "Angular" (bent) geometry arises when a central atom has two bonding pairs and one or more lone pairs. O in H2O has two bonds and two lone pairs → bent shape (≈104.5°). NH3 is trigonal pyramidal (one lone pair), SiCl4 is tetrahedral (no lone pairs on central atom), and H2CO (formaldehyde) is trigonal planar at C.
