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'.

Answer:
Latitude are the lines parallel with the equator, both above and below.
Longitude are the lines vertical from pole to pole, measured from the Prime meridian.
They are measuring lines used for locating places on the surface of the Earth. They are angular measurements, measured as degrees of a circle. A circle contains 360°. Each degree can be divided into 60 minutes, and each minute is divided into 60 seconds.
One degree of latitude equals 364,000 feet , one minute equals 6,068 feet, and one-second equals 101 feet.
One-degree of longitude equals 288,200 feet, one minute equals 4,800 feet, and one second equals 80 feet.
