• The answer when it is divided in the form of 5 blocks i think option A is suitable
  justification
  
  A)bcabc cabca cbcab bc
  see the pattern is 2 letters followed by abc or bca or cab like bc abc and ca bca cb cab and continues bc
  
  B&D)wrong because soon after a c will come and hence wrong same case for option D also
  
  C)in the middle if you observe the pattern 1->bcabc 2->babca 3->cbcab ac . end of 2 is a and beginning 3 is c so b is missing and hence option a is correct.
