• Addition of all the three digits of a number is an even number except 427.
  
  Elaboration:
  3+9+6=18
  4+6+2=12
  5+7+2=14
  3+9+6=18
  4+2+7=13
  6+7+1=14
  2+6+4=12
  
  Here we can see that all the results are even except
  4+2+7
  that is 13.
  
  Hence the answer will be 427 (b).

• 462-396=66 , 66 can divisible by 11
  572-462=110, 110 can divisible by 11
  396-572=-176 , 176 can divisible by 11
  427-396=31 not possible by 11
  671-427=244 not possible by 11
  264-671=-407, can divisible by 11,
  here 427 is odd out.
