CorrectNot quiteAnswer C

Correct answer: C

Try blocks of 4: _aa_ | ba_c | baa_ read against the shown letters.
The block baac fits: the first block needs b and c, the second needs a, the third needs c.
So the blanks are b, c, a, c, and the pattern is baacbaacbaac.

Worth noting

bcaa ends the third block with a, so it would read baaa instead of baac. After filling, reread the whole pattern block by block.
