Final answer:
The molecular geometry of ozone, O₃, is bent or V-shaped (option A) with a trigonal planar electron domain geometry and a central oxygen atom that is sp² hybridized.
Step-by-step explanation:
The molecular geometry of ozone (O₃) is bent or V-shaped. This is due to the presence of three nuclei and one lone pair of electrons on the central oxygen atom. With this arrangement, ozone has a trigonal planar electron domain geometry, but because the molecular geometry only considers the positions of the nuclei, not the lone pairs, the resulted shape is bent. Additionally, the hybridization of the central oxygen atom in ozone is sp², and the O-O-O bond angle is expected to be less than 120° due to the lone pair occupying more space.
