Show answer & explanation

Correct answer: D

Series: daa_bc_cda_a_c_c

We need to fill 5 blanks.

Let the blanks be:

daa bc cda a c _ c

Now check the pattern carefully in groups of 3:

  • daa

  • abc

  • cda

  • aac

  • bcc

Notice the letters are following a cyclic arrangement of a, b, c, d.

Fill the blanks one by one:

  1. After daa, to make abc → first blank = a

  2. bc_ → becomes bcc? No proper continuation. Taking pattern continuation gives second blank = c

  3. cda_ → next suitable letter = a

  4. a_c → middle letter = c

  5. Final _c → first letter = b

So the missing letters are:

a, c, a, c, b

Therefore, the correct answer is: option D
