Answer:
I believe the answer you're looking for is DNA, not sure though
Polar covalent because it is 2 nonmetals and the molecule has a net dipole movement.
I think it would be A because hazardous waste would most likely be found in dust, fumes etc. I'm not sure though.

They play a very important part. The geometry is not a straight line. It is an angle over 90 which means that the molecule has the same general shape as a boomerang.

But the two hydrogens and 1 oxygen actually look like the aforementioned boomerang.
