      }
      catch (InputMismatchException imeRef)
      {
            System.out.println("Exception "  
                             + imeRef.toString());
        }
        catch( IOException ioeRef)
        {
           System.out.println("Exception "
                         + ioeRef.toString());
        }
    }
}

Which of the following will cause the first exception to occur in the code in the accompanying figure?

If the divisor is zero

If the dividend is zero

If the quotient is zero
