The graph shows that the enzyme's activity increases with temperature up to a certain point, but then drops off rapidly after 40ºC. This suggests that the enzyme is sensitive to high temperatures and may denature or become inactive. The graph also shows that the enzyme's activity is almost completely eliminated at 55ºC, further supporting the idea that high temperatures are detrimental to the enzyme's function. There is no clear evidence of the enzyme having a cofactor or being affected by pH, so choices A and B are less supported by the data.
