PLEASE HELP BRAINLIEST AND 20 POINTS! Scientists have been studying threats to coral reefs. The shaded regions in the figure below show coral reefs that are at risk of disease. Explain the best way for scientists to test whether there are patterns in the spread of growth anomalies, which are widely spread on the figure.

A. Scientists could compare environmental conditions from various locations to find whether there is a similarity making corals in those regions susceptible.
B. Scientists could quarantine sections of coral reef until the situation resolves itself.
C. Scientists could raise temperatures near the affected reefs in the Pacific and Atlantic Oceans to see how the reefs respond.
D. Scientists could raise temperatures near the affected reefs in the Pacific and Indian Oceans to see how the reefs respond.
