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'.
The Earth is known to have five prevailing wind zones. They are:
- Polar easterlies is known to flow from polar high-pressure belt in the direction of the temperate low-pressure belts and it is said to blow from the east.
- Westerlies moves from from the west toward the east.
- Horse latitudes, found in the north and south and moves or flow toward the prevailing westerlies or equator.
- Trade winds flows mainly from east to west that is north and south of the equator.
- The doldrums starts at low pressure or weak pressure gradients, and moves in the direction of the trade wind of North and south.
Some of the examples of ocean Currents in the world are:
- North Equatorial Current is known to be a westward wind-driven current
- Kuroshio Current is known as north-flowing and also a warm ocean current .
- North Pacific Current is known to flow from west-to-east .
- Alaskan Current has its current flowing counterclockwise.
- Counter Equatorial Current is known as an eastward flowing and also a wind-driven current
- South Equatorial Current is known to flow from east-to-west. etc.
<h3>What is the link between wind and ocean currents?</h3>
The winds is known to be a weather condition that carries surface water with them which therefore forms currents.
Note that as these currents are said to flow westward, the Coriolis effect which is a force that emanates from the rotation of the Earth is said to lower their intensity which can make the currents to bend to the right, facing the north.

The question that Bill Clinton calls the urgent question of our time is weather or not we can make change a friend to us instead of it being an enemy. Basically ,he is saying we need to be flexible and ready to change because he believed that change was good for the country.
