In following questions, three sequence of alphabets/numerals are provided which correspond to each other in some way. Find out alphabets/numerals that come in the blank places.Choose the correct option

C B _ _ D _ B A B C C B _ _ 1 2 4 3 _ _ ? ? ? ? a _ a b _ c _ b _ _ _ _

Comparing position of capital letters, numbers and small letters, as we find:

a corresponds to C and 1 corresponds to a. So a and 1 corresponds to C.

b corresponds to A and 2 corresponds to b. So b and 2 corresponds to A.

Also, 4 corresponds to D.

So the remaining number i.e. 3 corresponds to B, So BCCB corresponds to 3, 1, 1, 3.
