d.23214244

• The correct question is:
  1, 11, 21, 1211, 111221, 312211, ______
  
  each term is the description of the previous term.
  see the second term it describes first term in numeric language:
  one 1 = 11
  now in 11 there are:
  two 1= 21
  now in 21 there are:
  one 2 & one 1 = 1211
  now in 1211 there are:
  one 1 one 2 & two 1 = 111221
  now in 111221 there are:
  three 1 two 2 and one 1 = 312211
  
  So the correct answer is 312211.
  provided options are not correct.
  and series goes like this:
  
  1, 11, 21, 1211, 111221, 312211, 13112221..... and so on
