We are given two series with missing letters:
aa_bbc_aa_b6cc and abbc_caa_bb_c
The underscores represent missing letters that need to be filled from one of the alternatives.
Let us analyze the sequences:
First sequence: aa_bbc_aa_b6cc
Second sequence: abbc_caa_bb_c
Check the logical pattern in missing positions:
For the first sequence, inserting "c" at the first underscore and "a" at the second underscore creates a repetitive pattern:
aa c bbc a aa c b6cc.
For the second sequence, inserting "a" and "c" in respective underscores maintains a repeating pattern.
Testing option (D) acbacac fills the blanks properly in both sequences preserving consistent letter patterns and no contradictory letters.
Hence, option (D) satisfies the sequence correctly.
