In temperate lakes during winter, the water column undergoes a process called "turnover," where the water becomes isothermal (uniform temperature) from top to bottom due to mixing caused by winds and changes in density. This would result in very little variation in temperature between the surface and the bottom of the lake. In contrast, tropical lakes typically have a stratified water column, where the surface water is warmer than deeper water, and this stratification is maintained throughout the year, making option C less likely.
