      B 1 : 2 Correct Answer Incorrect Answer
      C 3 : 1 Correct Answer Incorrect Answer
      D 2 : 1 Correct Answer Incorrect Answer

      Solution

      Radius of Hemisphere = r ∴  Radius of sphere = r/2 Volume of sphere = 4/3 π r³/8 Equate both the volumes: Hemisphere                           Sphere 2/3 πr³                                4/3 π r³/8 1                              :                  1/4 4                                  :              1
