Show answer & explanation
Correct answer: C
Correct answer: ffded
Explanation – The sequence repeats two 4-letter blocks: cfde and fcde.
Write the blocks consecutively: c f d e f c d e c f d e.
Place these letters into the pattern c _ d e _ c _ _ c f _ e: the underscores are filled in order by f, f, d, e, d.
Therefore the missing letters form the string ffded.
