for d, why would XeO3 not be considered T-shaped instead of trigonal pyramidal?

To be considered T-shaped, the VSEPR label thing (whatever it's called) is AX3E2. It has to have a lone pair on both the top and the bottom of the "T-shape" in order to take that form. With just the one lone pair, the bonds will be repelling from the lone pair, rather than getting caught in the middle of the two. I hope this helps. :)
