Since 1979, there has been a decline in both the minimum extent of summer sea ice and maximum extent of winter sea ice. Option A is incorrect as it states that summer sea ice has gradually increased since 2001, which is not true. Option B is incorrect as it contradicts itself by stating that "most to all sea ice melts" and then says "less water has been refreezing over the past decade." Option C is incorrect as seasonal variations in sea ice extent have always occurred, and it is not a recent phenomenon.
