38. Two bitumen samples “X” and “Y” have softening points 45°C and 60°C, respectively. Consider the following statements
    :
    I . Viscosity of “X” will be higher than that of “Y” at the same temperature.
    II . Penetration value of “X” will be lesser than that of “Y” under standard conditions.
    The CORRECT option evaluating the above statements is
    

1. 1. Both I and II are TRUE
      

   
   
   

   2. I is FALSE and II is TRUE
      

   
   
   

   3. Both I and II are FALSE
      

   
   
   

   4. I is TRUE and II is FALSE
