The incorrect geometry is represented by: AsF5- trigonal bipyramidal, BF3- trigonal planar, NF3- trigonal planar, H2O- bent

NF3 has trigonal pyramidal geometry. N atom has one lone pair and three bond pairs of electrons. The electron pair geometry is tetrahedral and molecular geometry is trigonal pyramidal. The bond angles are lower than tetrahedral bond angles due to lone pair - lone pair and lone pair-bond pair repulsions. N atom is sp3 hybridised. Hence, option A is the answer.
