I think it's A but here's an explanation anyway: as you heat the crude oil, the different hydrocarbons, having different boiling points, boil and evaporate up the column. Those with lower boiling points, shorter in chain length, will condense nearer the top of the fractional distillation column. Those that are more viscous, larger in chain size, will have high boiling points, so will evaporate last and condense lower down in the column. Therefore, you achieve all the different oils / materials (oil, petrol, gasoline, tar etc etc). I hope this helps. If not, then a good website to use is 'BBC bitesize, fractional distillation'.
Pretty sure its c. From the text you provided me

Geographers use map projections to translate the planet in a two dimensional representation. Unfortunately, you can’t display 3D surfaces perfectly in two dimensions, distortions always occur. There are many different projections that are commonly used throughout the world.
