The correct answer is

d d f e e d e e

To solve this problem, we need to find the correct sequence of letters that fill in the blanks of the letter series: f d _ e _ e f _ d d _ d _ f f _ d _ d _ f. The given options are:

  • d d f e e d e d
  • d d f e f d e e
  • d d f d e d e f
  • d d f e e d e e

Let's analyze the pattern in the given letter series:

  1. The series consists of sequence repetitions. We look for a cyclic pattern.
  2. By examining the given sequence, observe the segment "f d _ e _ e f", which appears to repeat in similar patterns.

Let's check the given correct answer option: d d f e e d e e.

  • Substitute the blanks with "d d f e e d e e", we get the sequence: f d d e e e f d d f d e f f e d e d e f.
  • This forms a repeating pattern: f d d e e e f.
  • The next section, starting with 'e', correctly continues to form a similar sequence pattern.

Thus, we confirm the sequence follows a repeating pattern. Based on cyclic repetitions, the appropriate option is d d f e e d e e.

Hence, the correct answer is:

d d f e e d e e

This pattern ensures the logical consistency of the sequence with identically repeating sections, validating the answer choice.
