It is common for freshwater lakes near or above a latitude of north of the equator, like Lake Mjøsa in Norway, to accumulate surface ice in winter. The amount and duration of ice depends on many factors, including local weather conditions as well as the lake's depth, volume, and surface area, but a climate researcher claims that some lakes in these latitudes have seen a decline in the duration of ice between the early 1980s and the mid-2000s.
Which choice best describes data from the graph that support the researcher's claim?
Näckten had approximately 175 days of ice in the winter of 1980-81 and approximately 135 days of ice in the winter of 2005-06.
A
None of the three lakes had fewer days of ice in the winter of 1980-81 than they did in the winter of 2005-06.
B
Spirit Lake had approximately 100 days of ice in the winter of 1980-81 and approximately 125 days of ice in the winter of 2005-06.
C
The highest number of days of ice a lake in the graph had in the winter of 2005-06 was approximately 135.
