Scientists collect data regarding Earth's surface temperature over the last 900,000 years using direct and indirect methods. If they construct a graph of this data, which statement best describes the graph? NEED HELP ASAP!!!!

A The graph would have a fairly straight line with a sharp curve upward to show recent rising temperatures.

B
The graph would show stable temperatures followed by a sharp curve down as temperatures cooled.

C
The graph would start low, and then curve upward significantly to show a rapid rise in average temperatures.

D
The graph would have both highs and lows to show the periods of warm and cool temperatures.
