From 2, Mr.Sushant’s sister is either wife of Mr.Sharma or wife of Mr.Sharma’s brother.Mr.Sharma has no sister.Mr.Sharma’s father has two children.It means that Mr.Sharma has two sons.Thus,the exact relation can’t be established.

   Data given in both statements ‘a’ and ‘b’ are necessary to answer the question.
   Option D
   From 1 and 2 alone ,we can’t get the answer so we combine both.There can be three cases.
   CASE1 : X is third heaviest. Z is not the second heaviest student.W ,who is not the heaviest,is heavier than Z and weight of atleast one student lies between W and Z.So, W is second heaviest and Z is lightest. V is not heavier than W. V is second lightest student and Y is the heaviest student.
   CASE 2: X is second heaviest. W,who is not the heaviest ,is heavier than Z and weight of atleast one lies between W and Z. W is third heaviest person and and Z is lightest. V is not heavier than W. V is second lightest and Y is heaviest
   CASE 3 : X is heaviest. Z is not the second heaviest person. W who is not the heaviest ,is heavier than Z and weight of atleast one lies between W and Z. So, W can be second or third heaviest . Thus,either none or none person is heavier than Y.
