SPM 2012 Paper 1 Question 25  
  1. The melting point and boiling point of  V and W are lower than 1000C. Both exist as solid at 1000C. 
  2. The melting point of  X is lower than 1000C. The boiling point of X is higher than 1000C.  It exists as liquid in room temperature.
  3. Both the melting point and boiling point of Y are lower than 1000C.  It exists as gas in room 1000C. 
The correct answer is : C
