Two molecules have the same molecular geometry but different electron domain geometries. Which combination of atoms and lone pairs around the central atom could describe these molecules?

In choice D, both molecules have two atoms bonded to the central atom, so each has a bent molecular geometry. With two lone pairs, the first has four electron domains and a tetrahedral electron-domain geometry; with one lone pair, the second has three electron domains and a trigonal-planar electron-domain geometry. Thus, their molecular geometries match but their electron-domain geometries differ.
