            1.  Assertion: In Classification the data is classified according to the labels.
               Reason: This model works on discrete dataset which means the data needs to be continuous.

               (i)  Both A and R are correct and R is the correct explanation of A.
              (ii)  Both A and R are correct but R is NOT the correct explanation of A.
              (iii)  A is correct but R is incorrect.
              (iv)  A is incorrect but R is correct.
          Ans. (iii) A is correct but R is incorrect.
