Explanation:

Correct Option: (c) Explanation:  Both statements are correct. Supplementary notes: Isotherms  The Isotherms are lines joining places having equal temperature. In the northern hemisphere the land surface area is much larger than in the southern hemisphere.  Hence, the effects of land mass and the ocean currents are well pronounced. In January the isotherms deviate to the north over the ocean and to the south over the continent. This can be seen on the North Atlantic Ocean.  The presence of warm ocean currents, Gulf Stream and North Atlantic drift, make the Northern Atlantic Ocean warmer and the isotherms bend towards the north.  Over the land the temperature decreases sharply and the isotherms bend towards south in Europe.  The effect of the ocean is well pronounced in the southern hemisphere. Here the isotherms are more or less parallel to the latitudes and the variation in temperature is more gradual than in the northern hemisphere. The isotherm of 20°C, 10°C, and 0°C runs parallel to 35°S, 45°S and 60°S latitudes respectively.
