Select the combination of letters that when sequentially placed in the blanks of the given series will complete the series.
b _ c _ d _ k b _ _ a _ e k b b _ a d _ k

  1. A
    b a e b c d e c
  2. B
    b e a b c d c e
  3. C
    b a e b c d c e
  4. D
    b a e d c d c k

Solution & Step-by-step Explanation

Let's count the total number of characters including blanks. There are 21 positions.
Let us test the combination from Option C: b a e b c d c e

Placing them in the blanks sequentially:
1st blank → b
2nd blank → a
3rd blank → e
4th blank → b
5th blank → c
6th blank → d
7th blank → c
8th blank → e

The complete sequence becomes:
b b c a d e k | b b c a d e k | b b c a d e k

This forms a perfect repeating pattern of a 7-letter block: bbcadek.
