B: What kind of three-dimensional geometry would this molecule have?

C: Would this molecule be polar or nonpolar? Explain your answer.

B: “Triangular Planar”.

C: I've tried to answer this question. I know a polar bond is when the electronegativities of the atoms differ and a dipole may form but I'm just not sure on how to explain this.

You can't get spacing on these boards so it's almost useless to try. Here is a site that shows H2S. It is angular, like H2O, and has a dipole moment.
Here is a site or two that may help visualize it. (The electronic geometry is tetrahedral.)
