Consider the following statements :Statement-I :The temperature contrast between continents and oceans is greater during summer than in winter.Statement-II :The specific heat of water is more than that of land surface.Which one of the following is correct in respect of the above statements?

A Both Statement-I and Statement-II are correct and Statement- II is the correct explanation for Statement-I
B Both Statement-I and Statement-II are correct and Statement- II is not the correct explanation for Statement-I

Explanation

  1. A

    Both correct and II explains I. The land–sea contrast is greater in winter, not summer.

  2. B

    Both Statement-I and Statement-II are correct and Statement- II is not the correct explanation for Statement-I

    Both correct but II does not explain I. I is false.

  3. C

    Statement-I is correct but Statement- II is incorrect

    I correct, II incorrect. Water’s specific heat is higher than land’s.

  4. D

    Statement-I is incorrect but Statement-II is correct

    I incorrect, II correct. Continents get colder than oceans in winter; water’s high specific heat is why.

Summary. Official key is (d). Oceans warm and cool slowly because water’s specific heat is high. The sharpest continent–ocean temperature contrast is in winter (very cold interiors, milder seas), not summer. Statement-I reverses the season; Statement-II is true.
