a 2000
b 1957
c 1917
d 1954

Explanation:

To determine the year with the greatest number of sunspots, we analyze the graph. The vertical axis represents the number of sunspots, and the horizontal axis represents the year. By visually inspecting the peaks (highest points) of the plotted data points, we compare the years associated with these peaks. The peak around 1957 (option b) is the highest among the given options (2000, 1917, 1954, and 1957).

Answer:

b. 1957
