Answer:
C. Solar radiation has the greatest effect on a season's climate. Solar radiation from the sun is the primary source of energy that drives Earth's climate system, and it varies over time and by location. The amount and intensity of solar radiation reaching the Earth's surface affect temperature, precipitation, and atmospheric circulation patterns, which are key factors in determining a season's climate. Global wind patterns and ocean currents are also important factors that influence climate, but they are ultimately driven by the distribution of solar radiation across the Earth's surface.
