• answer is D...lets take 1st draw is BLUE..then there is a chance of getting BLACK for next 14 draws as there are 14 BLACKS..now we have finished 15 draws..now on 16th draw we will definately get blue..:)

• We usually try to apply worst case scenario(which will be pseudo) and forget to find the optimal feasible solution,
  Sufficient condition to get a pair of socks of same color is just 3, because after drawing 2 socks,
  In worst case both of them will have different color and the third one to be drawn should make a pair with already available one of that color,
  In best case drawing 2 itself would have fetch pair of same color.
  
  So the answer is >2.
  
  2 may be enough, but will not be sure.
  3 is enough to get for sure.
  16 is sufficient to the get pair of both the colors .
  
  If these kind of question is asked in any interview then the answer should be number of different colors + 1.
  That +1 to make pair.
  
  So here the answer is 2+1 = 3

  first 14 is either blue or black.after that 15th is one of the remaining color.
