The correct option states that Statement-I is incorrect while Statement-II is correct due to the differing heat capacities of water and land. In summer, oceans, having a higher specific heat than land, absorb more heat and warm slowly, thus reducing the temperature contrast, while in winter, land cools more rapidly than water, leading to a greater contrast in temperatures. This contributes to more stable weather patterns over oceans compared to the more variable conditions over continents, aligning with the principles taught in standard UPSC-level sources about climate and meteorology.
