The question indicates a time frame from 1982 through 2010, and the best description of the changes in average annual SST during this period is that it steadily increased. Options A and D are contradicted by data from several sources, including the National Oceanic and Atmospheric Administration (NOAA), which consistently show an overall warming trend for SST over the past few decades. Option B is partially correct in that SST did increase until 1993, but it then continued to rise until at least 2010, which is the endpoint of the question's time frame.
