Final Answer:
Considering the isotherms and the shading scale for temperature anomalies to the right, the magnitudes in the greatest negative SST anomalies are between -3 to -4 Celsius degrees.
Option C is answer.
Step-by-step explanation:
The question pertains to the interpretation of sea surface temperature (SST) anomalies based on isotherms and a shading scale. The correct option is (c) -3 to -4 Celsius degrees, indicating that the greatest negative SST anomalies fall within this temperature range. Negative anomalies suggest temperatures lower than the average for a specific period. In this context, the isotherms and shading scale likely represent deviations from the normal SST, and the range -3 to -4 Celsius degrees signifies the magnitude of the most significant negative anomalies observed in the given data.
Option C (-3 to -4) is the answer.
