Sunspots are dark areas on the surface of the Sun. They mark strong magnetic fields, and more sunspots indicate that the Sun is more active and is releasing more energy. The following graph presents the average daily number of sunspots from 1900 through 1944. Each data point is the average for one month. Notice the series of peaks and troughs in the graph. The time from one minimum (trough) to the next is called a Solar Cycle. Solar Cycles can be anywhere from 9 to 14 years long.

What can be predicted with the most certainty from this graph?
A.
The next minimum in the graph will be in 1953.
B.
The average daily number of sunspots will peak in 1949.
C.
The average daily number of sunspots in 1949 will be 80.
D.
The average daily number of sunspots will increase throughout 1945.
